Tension(s) used for playtest: 55 lbs (I strung a 2nd racket with 4G 1.25 at 55lbs to test side by side with the Prototype)
Regular string set up: Babolat Hurricane Pro / Luxilon ALU Rough (55/52) on a Wilson RF97A
Racquet brand and model used for test: Wilson H22 16x19
Power of test string: The power level is right where I like it. It gave me enough power where I can hit a winner on an easy ball, but not overhit on a rally ball. Side by side, it felt a little more powerful than the 4G.
Feel (Stiff? Mushy? Muted? Crisp?): The string felt very crisp. I like how the ball jumped right off the stringbed. Compared to the 4G, the ball dwelled on the strings a little longer, resulting in some missed precision.
Spin: Both the Prototype and 4G showed similar amounts of spin. Neither particularly more than the other. Not as much spin as a Babolat RPM Blast.
Comfort: For a poly string, it definitely feels comfortable. Much softer than my regular setup.
Durability: After my first 5 min session with the Prototype, I could already see some light fraying off the strings. Getting some slight notching about 2 hrs in. Whereas the 4G in the same amount of time, did not show the same signs of wear.
Playability Duration: (share thoughts on if/how the playability changed over time): Playability is pretty consistent after 2 hitting sessions. Strings have started to move slightly after 2 sessions and 3 doubles sets.
Control (predictable trajectory? Easy to control depth? performance on different strokes and swing speeds?): Definitely benefits the faster rackethead speed. Very easy to control on short cuts, and allows for line licking shots on the full swing. My backhand definitely reacted very well to these strings.
Compare to the string you use most often: Compared to my regular strings, the Prototype definitely is a plus in the power, feel, and spin department. These strings are softer than my regular setup, but I actually do like that bit of stiffness to feel the ball a little more.
Tension recommendations (after hitting it, would you recommend a different tension? If yes, why?): I think a starting tension of 55 on a 98 sq in. worked well for me. It wasn’t too low or too high. I could play myself into a comfort zone at this tension.
List any additional thoughts (optional): Having strung these strings for a player at Indian Wells, I was very intrigued at trying them out. First off, I love the color. Having now actually hit with them, this string feels really great. I definitely like it more than the 4G that I was using side by side. It was also easier to string than 4G (I always have trouble stringing 4G). I’m not sure how much of a difference it will make in my regular setup if I swap out my ALU Rough for the Prototype, but it will be worth a try. Or maybe, I can possible just go full bed Prototype strings instead. Thank you so much TW for giving me a chance at testing this string.
