Hi all. I'm looking to put together a demo list to order from TW. If anyone has suggestions or personal experience with these racquets, please post some info! Also, if you need more info about anything, feel free to ask. Style of Play: - 15 Years Old - I've never been rated but I'm competitive with a 3.5 adult male. - SW Forehand - 2HB, Continental-SW - 60% of the time I'm at the baseline, 40% at net. I try to serve and volley at least once per game. Current Racquet: I'm using a Wilson [K] Four 105. I bought it last year when I started doing a tennis camp. It's been good but here's what I'm looking for in improvements: - I'd like something less stiff. - The [K] Four feels way too hollow... I don't like this at all. - I'm looking for a slightly smaller head size. - I also want to try out racquets that are more head-light. - I definitely want more weight on the racquet. The [K] Four is too light for me at about 10 oz. Demo List: So far, these racquets look like they fit the specs I'm looking for: Wilson K-Surge Wilson N-Pro Open (I also see the updated K-Pro Open, but I find it hard to believe that the extra $100 is worth it.) Wilson KSix Two Yonex RQ iS 2 Tour I've solely used Wilson Racquets so far in my life (starting with those cheap $29.99 ones at sports stores). I'm hoping that switching to a different brand won't be that drastic of a change. Also, I notice that I've mostly limited my search to the Wilson line. Any info about other brands is appreciated also. Thanks in advance!
