Wilson Labs ‘Project Shift’ 99 315g/18×20 Review

Having previously tested the 300-gram version we were fascinated by what the lateral-bending technology would bring to a heavier frame with a much denser string pattern, usually a recipe for much flatter, direct, and pinpoint shots. 

Both this model and its light sibling share the same beam profile (a constant 23.5mm) and stiffness (RA of 68) so the in-hand experience was familiar. But the substantial difference in weight coupled with the 18×20 string bed was transformative. Instantly we could see the ball trajectory had flattened significantly and our shots stayed much lower through the court. The rainbow flight was replaced by a more bullet-like shot shape.        

This said, however, in contrast to other frames from different manufacturers that share similar characteristics, Wilson’s proprietary bending technology does make a genuine difference. Substantial, densely-strung frames can be hard work for all but the strongest of players, but Wilson is making this type of frame an option for a wider range of players with the way in which it bends to help accentuate spin. 

Don’t get us wrong, the demographic for this particular model is still smallish, but if your game style is focused on power and accuracy as opposed to all-out spin, this could answer your prayers.   

Ultimately, we loved the heaviness and accuracy that this frame provides, with just a hint more spin than you would expect from reading the specifications. You do still have to be a stronger player with solid mechanics to get this frame to excel, but thanks to Wilson’s new technology it is playable enough for good players keen on hitting with accuracy, heaviness, and plow-thru.

We tend to avoid bigger frames for players who live for volleying. Having had mixed results with the 300-gram version of the Shift, we were skeptical about how well this model would perform at the net. However, we were very pleasantly supplied. 

All 315 grams helped make volleying a pleasure. There was no instability and very often, merely allowing the racket to ‘get in the way’ of the ball worked. But being more assertive and adding a little punch to your volleys will send the ball away with real accuracy and authority.

Naturally, the 18×20 string bed promotes strong directional control and the feel was nice with the lateral-bending serving to soften the impact and allow for a degree of subtlety too. Overall, for capable racket handlers and adept volleyers, this racket will not let you down. 

If the 300-gram iteration was good for serves with spin and kick, the heavier model lent itself more towards missiles that scudded through the court with a fair amount of heaviness. 

Of course, you need to be physically capable of getting a 315-gram frame moving at speed to maximize its potential, but if you have that capability this racket will reward you with pinpoint missiles that will challenge most opponents. 

Our initial serves were lackluster but once our engines were fully warmed-up things got very interesting. The direction was of no concern thanks to the string pattern, we could choose our spots, and providing our technique was on-point, the Shift would do the rest. 

Serves that kicked and fizzed were somewhat of a challenge and maybe a change of string/tension would pay dividends when it comes to adding more revolutions to the ball, but for straight-line bombs that keep accelerating, we had no qualms about this racket whatsoever.

Against powerful servers, the frame allows you the option of ‘getting in the way’ with a blocked return and there will still be a little interest on the ball. The way in which the frame bends adds something to this type of approach and the 315-grams of mass functions well when you are looking to literally block. 

At 99-sq inches and packing extra grams, it is fair to say that there are more maneuverable options available, but again, if you are a reasonably strong and accomplished player and can wield this type of frame with relative ease, returning can be a joy, even against the most fearsome of servers.   

Ultimately, along with serving, returning is maybe the one area where this frame needs the user to bring something to the table in order to get the most out of its potential. But for those who can provide their own power and speed, this model is a legitimate weapon. 

Wilson has genuinely conjured up something genuinely new with the Labs Project Shift 99 (315 grams/18×20). Rather than rehash old formulas with slick marketing they have given the consumer both an innovative and rewarding experience. 

Actually, the initial release of this model is a ‘work in progress’ project with the Wilson ‘Labs’ moniker reflecting that this iteration of the Shift is effectively a glorified proto-type, manufactured in limited volumes until Wilson can make refinements to please its audience.  

You will find on each frame a QR code that once scanned takes you to an online questionnaire designed to collect player feedback on the racket. Wilson will process each response and the collated feedback will be used to direct final modifications before a full-scale production model is released – and by all accounts, the final release will be in a completely different color too!

Wilson has legitimately tried to offer something that will fill a unique niche within the wider racket market. At 99-sq inches the Shift speaks to those who need a little bit of help with forgiveness and playability, while it also seeks the attention of better players desiring a turbo-boost for their game, especially with this heavier option.

The ‘lateral flexibility’ technology actually works and it is not a gimmick. It enables the frame to accentuate spin and feel without being too harsh, even though it has a comparatively high stiffness rating (RA) of 68. 

The new technology does not transform an 18×20 string bed into a spin monster, but it does make a noticeable difference. Enough to broaden the appeal of such a frame – something that will make the recommendations within our custom fittings a lot more interesting!
