I've got three doubles matches in with the new Speed Pro's, will have just a hit session tonight. The new Speed Pro is familiar yet definitely different. I really like the feel of the 360+ frames and the new Auxetic feels good, but for me there was a slight learning curve. New sticks both came in pretty much on spec... 327g with the placard and plastic on the grip. Once I strung up with 17ga HyperG (46lbs) and added overgrip I was at 329g and 6.5pt HL balance.
I immediately went out and played a doubles match. Right from the start I struggled to find my range and feel in warmup. Ball seemed to be launching a little bit and spin was just not as easy to come by. I did notice when I was stringing that racquets that there seemed to be an unusual amount of frame flex when stringing. Maybe with the white frames of the 360+ I never noticed it, but man these Auxetic frames really seemed to move a lot under tension.
I was disappointed with the new frame... but started thinking about what I saw when stringing and what was happening on the court. Yesterday I restrung with Alu Power 16L and bumped to 50lbs. In warmup the difference was immediate... contact felt great... balls had good pop, but I could hit with spin, flat etc. without fail. Stringbed went from unpredictable to perfectly predictable. With enough tension... this frame has a really rewarding 'poppy' feel at contact.
The sweet spot feels bigger and more responsive with the new frame, but still very predictable. With the new setup I played lights out tennis. Volleys, groundstrokes, serves were all great. Volleys were especially nice with the new Auxetic feel. I think there is a touch more pop accessible in this frame. Regardless of the lower tension or higher tension... this frame serves even better for me. Easy, big flat serves... spin serves were very easy to hit as well.
All in all... a nice improvement in feel while still playing like the Speed Pro. If you have a 360+ and like it the new Auxetic version is an evolution, not a revolution. Still it'd be worth demoing just to see if the new improved feel might benefit you. Stringed is more responsive while still being very predictable and that's my favorite thing about the new version. Just keep in mind that I really believe that this racquet prefers to be strung with a firmer string or at higher tensions based on the way the frame reacts.
