Executive Summary
The Wilson H22 is a pro stock frame mould — not a retail product — that has become one of the most recognisable and sought-after frames in professional tennis. "H22" refers to the mould designation in Wilson's internal system, and it has been the structural foundation for some of the most successful player's frames in tour history.
Key Characteristic: The H22 mould produces a frame with a narrower throat, slightly different hoop geometry, and weight distribution characteristics that many professionals describe as producing superior feel and plow-through compared to cosmetically equivalent retail frames. The difference is subtle but real — particularly in stability at contact and vibration transmission through the handle.
Key Positioning: The H22 sits firmly in the classic player's frame category — low power, high control, heavy and demanding. It is unambiguously a frame for advanced and professional players with complete, confident ball-striking. Players who use the H22 mould are making a statement: they want to feel everything, compensate for nothing, and trust their technique entirely.
Performance Profile
The H22 mould prioritises touch, stability, and plow-through above all else. It offers minimal power assistance, demanding that players generate their own pace through technique and physical commitment.

Model Context
The H22 is a mould, not a named retail product. Understanding its relationship to Wilson's retail lines — and how tour players disguise it — is essential context for interpreting equipment data.
H22 Pro Stock
The bare mould, sometimes available through pro stock suppliers. Typically 316–320g unstrung before customisation. Tour players add significant lead tape, silicone, and leather grips to reach their target weight and balance — often 340–360g strung.
Blade Pro (H22)
The retail frame sold under the Blade Pro name, built on the H22 mould. This is the closest publicly available version of what tour players use. Heavier and more demanding than the standard Blade 98 series — it makes no concessions to accessibility.
Blade 98 v8 (16x19)
The mainstream retail Blade. Built on a different mould (K7) than the H22, it is lighter, more accessible, and more forgiving. A very fine player's frame in its own right — just not the same geometry as the H22 that professional players prize.
Technical Must-Knows
Who Plays With This?
The H22 mould is favoured by players who prioritise feel and stability at the highest level. Tour frames built on this mould are almost always significantly heavier and more customised than any retail version — these profiles reflect playing style, not identical specifications.
Khachanov's powerful, flat-hitting baseline game — built around one of the biggest forehands on the ATP tour — demands the plow-through and stability the H22's mass-heavy configuration provides. His full, aggressive swing can load a high-swingweight frame effectively, generating the momentum needed to drive through the ball with authority on both wings.
The young Peruvian professional represents the next generation of H22 users — players who began their careers with the Blade Pro variant rather than seeking out bare pro stock. His powerful baseline game and athletic build allow him to benefit from the frame's demanding stability and precision characteristics.
O'Connell's solid, professional-level game relies on consistency and physical endurance rather than singular power. The H22's stable, heavy feel complements his full-swing groundstroke style and gives him the reliable platform he needs to compete at the highest level over extended matches and seasons.
String Setup Guide
The H22's flexible beam and high swingweight (in customised form) make it highly sensitive to string choice. The frame's feel-first character rewards strings that amplify touch and precision. Reference range (H22 / Blade Pro): 46–58 lbs (21–26.5 kg).
Quick Start (Most Players)
- Start point (co-poly, 1.25mm, full bed): 48–52 lbs (21.8–23.5 kg) — the flexible frame at moderate tension produces an excellent blend of feel and control without feeling stiff or wooden.
- If the ball is flying long: Add 2–3 lbs or use a slightly firmer poly (1.27–1.30mm). The 16x19 pattern is relatively open — tension is the key control variable in this frame.
- If you want more spin: Drop 2 lbs and try a shaped co-poly. The 16x19 provides good snapback geometry — shaped strings maximise this effectively.
- If your arm is struggling: The flexible beam helps significantly. At lower tension (44–48 lbs) with a multifilament or natural gut, the H22 becomes one of the more comfortable tour-spec frames to play with regularly.
- Highly customised frames: If you've added significant lead tape to the H22, recalibrate tension — a heavier frame with higher swingweight may require 2–4 lbs lower tension to maintain the same pocketing sensation.
Pro Reference
Setup idea: Luxilon ALU Power 1.25mm full bed, reported at mid-50s lbs tension.
Khachanov's preference for ALU Power reflects the tour's most popular co-poly pairing with the H22. The aluminium-alloy composition provides the crisp, direct response that suits his aggressive, flat-hitting style. At his ball speed and swingweight, the ALU Power delivers the directional control and tension maintenance needed through extended baseline exchanges. Tour setups vary — use as a directional reference only.
Recommended Setups by Goal
| Goal | Recommended Setup | Starting Tension | What You'll Feel |
|---|---|---|---|
| Balanced | Co-poly (full bed), 1.25mm | 48–52 lbs (21.8–23.5 kg) | Clean, precise response with excellent feel through the handle — the H22's signature |
| More spin | Shaped poly mains (1.25mm), optional soft crosses | 46–50 lbs (21–22.7 kg) | More bite at contact — the 16x19 pattern provides good natural snapback, shaped strings add to it |
| Maximum control | Firm poly (ALU Power, 1.25mm) | 51–55 lbs (23–25 kg) | Surgical directional precision — Khachanov's territory. For elite full-swing baseliners only. |
| Premium feel | Natural gut mains + ALU Power crosses (hybrid) | Gut 53–57 lbs / ALU 49–53 lbs | Exceptional comfort and touch — the classic pro setup for players who prioritise feel above all |
| More comfort | Multifilament full bed or hybrid with soft cross | 46–50 lbs (21–22.7 kg) | Soft, forgiving impact — unlocks the H22's arm-friendly potential fully |
Maintenance Rule
- The H22's flexible beam amplifies the difference between fresh and dead poly. A fresh poly in this frame feels alive and connected; a dead poly feels like hitting with a plank. As a heavy, demanding frame, the H22 accelerates string fatigue — restring proactively at 15–25 hours for poly setups, or when you notice loss of pocketing and the characteristic H22 feel.
Top 3 Recommended Strings
These strings consistently perform well in the H22 and Blade Pro, based on tour data and community feedback. The flexible beam rewards strings that complement feel and precision — a firm poly at high tension will make the frame feel harsh and stiff rather than revealing its true character.
Best for: Advanced players (4.5+) wanting the classic pro stock feel with maximum directional precision.
The most widely used string among H22 users on tour. Luxilon ALU Power's aluminium-alloy composition creates a crisp, defined response that is perfectly matched to the H22's precision-first character. Outstanding tension maintenance, excellent control at high ball speeds, and a satisfying, connected feel through the handle. The gold standard pairing for players who want maximum directional control.
Best for: H22 users who want to add spin without leaving the Luxilon ecosystem.
The octagonal shape creates meaningful bite at contact — useful in a 16x19 pattern where snapback already provides good spin potential. Pairs the familiar ALU feel with enhanced topspin capability. Slightly thicker gauge compensates for faster wear from the shaped profile. String 2 lbs lower than equivalent round ALU setups.
Best for: Feel-first players and those managing arm sensitivity who want the ultimate touch experience from the H22.
The classic pro hybrid — natural gut mains for elasticity, comfort, and exceptional feel; ALU Power crosses for control and durability. In the H22's flexible frame, this combination produces an unmatched sensation: plush, connected, and incredibly responsive to touch. The gut mains reveal every nuance of contact; the ALU crosses prevent the bed from moving too freely. Used by many tour players seeking maximum feel.
Pro tip: The H22 is deceptively sensitive to customisation weight and string tension together. If you've added lead tape, adjust tension downward by 1–2 lbs per 3–4g of lead added. The increased swingweight will amplify the frame's power slightly — compensate with tension rather than adding more weight.
