Hit and played 2 hrs with it, am an all court 4.5 player. Have used a ton of rackets in the 11-11.5 tweener area. Most recently played with RDS002 (lighter one), Aerogel 500, and Pure Storm team. The TFlash specced out at 11.5 oz and about 7 pts HL stock w/dampener. What stood out - easily most solid/stable and "player like" of the rackets mentioned above and almost all of the 11 -11.5 oz frames. Racket was great at volleys (simply rock solid) - touch volleys not quite as good as the normal ones - but still good. Groundstrokes: For my game just about the perfect blend of controllable power pretty consistent stringbed. Could generate consistent depth wih spin very easy to access. Hits a pretty heavy ball, what I really noticed was that the ball drove through the court better than most rackets in this category. Forehand: Was the shot that really stood out for me, the more "head -like" grip meshed well with my SW forehand. Could flatten it out or hit a hit topper with ease. For some reason could really punish short balls with consistency. Backhand - 1H: Here was the most difficult adjustment and I think it was mostly the grip shape, I hit it okay but was constantly searching for the "right grip" - when I had time and found it was very solid. I think this is simply more of an adjustment than anything else. Slice backhand was solid. Serve: My serve is okay/solid and that's how I felt serving with this stick. Was very consistent with placement and had solid pace. For me a better serving stick than RDS002 or Pure Storm team, about equal with AeroGel 500 tour. Pretty decent kick. it was only one day and I feel more adjustment is needed. Feel/Comfort: For example, had much better "feel" than the Aerogel 500 tour that has none for me, could just barely feel the racket flex some which was actually about right for me. I strung it with ArmourPro gut mains/ Rip Control X's as I have a sensitive elbow and shoulder - felt fine with this setup at 53-54 lbs. Summation: Is it a lighter more powerful player's racket? or a heavier tweener? This frame stock, with NO needed lead additions (which I have grown tired of!), really seems to bridge that gap for those who can't handle a 12oz or higher stick, but find the 11oz tweeners too much of a change. So far I'd say Technifibre has filled that niche nicely with this frame. I need a lot more play with it, should be an excellend dubs frame as well. Well worth a Demo for those looking for a frame in this category.
