Hi. Im playtesting Genesis Spin X (just finished), and plan on testing Topspin Concept Pure next. (link to original thread, http://tt.tennis-warehouse.com/showthread.php?t=279219&highlight=genesis+spin) Some background info on me: 4.0-4.5 all courter. Big Forehand and prefers serve placement over speed. Comes up to net as much as i can. I put different amounts of topspin depending on what i need to do, i can hit flat or with a lot of topspin (First 1.5 hours with spin x) Groundstrokes- 7/10. They were mediocre. Nothing special. I don't think the texture gave any extra spin. Pretty good with directional control but thats about the only outstanding thing about it. Volleys- 8/10. Another avg part of the string, feel isnt quite there. Serve- 5/10. Absolutely miserable. Uneasy access to spin, placement was off, speed went down. Overall, compared to my control string Pro Supex Big Ace, this string is rated below it for me. BA does everything better except maybe tension maintenance. I plan to play with this string for a bit more and see if it requires a break-in time. I will update this after playing with it again. I just tested the string out for 5 more hours and i have some different numbers now. First off, serves were much better, I could get some nice speed off my flat serves although placement just wasnt there. Groundstrokes were about the same, maybe a little more pop but not a lot. Volleys now are 9/10. They have a pretty nice feel for a textured string and good touch. Side note: Although Spin X is a textured string, there is really no outstanding difference to a regular poly. not really any extra spin and not really board-like. _________________________________________________________________ Topspin Concept Pure Stringing: Stringing was as easy as Big ace and bouncing the ball on the strings, there is a sense of increased dwell time. Hopefully there is a bit more spin off this string than with Spin X Playtesting hours- 2 hours Groundstrokes- 10/10- Spin is amazing, control is pinpoint, just enough power to put away balls when you need to. One of the best strings I have ever tried. Volleys- 9/10- Great feel on volleys, you can send them deep or sharp angles with ease. Nice pop Serve- 9/10- Nice spin, power and placement from this string. kick serves were nice and flat serves were bombs. I played extensively with this string and have used 1 set for well past 15 hours and it is still playing almost as well when freshly strung. Great string imo. ______________________________________________________________________________________________________________________________________________________________ Next string is Leopard control team 16.
