Good time to see someone like you who'd owned all 3 of those rackets.. (sorry about my english).. that been said. Well, I picked up the ezone 100 because, at the beginning, I liked the power, feel and the large sweetspot in comparison with T Fight 300 RS(Wich is also a great all around racket). The ezone make me hit with more confidence, I was playing well and that's the problem. I'm a flat hitter player, so I started to hit more agressively(because I was more confident) and most of my balls were flying out (and I have to agree with you about serving out of the sweetspot). I was upset with this and took my friend's blade 98 18x20 Amplifeel to play a for a while and compare them. When I started to play with blade I could hit hard and had no concerns about balls flying out, so I was playing agressively and with good control. The downside was the small sweetspot. But after that I started to think if was not the case of switching to a Tecnifibre TF40 305 18x20 ou even a speed pro, wich is also 18x20 and are getting excelent reviews. I'm afraid of picking up the speed mp and continue to make the balls flying out the court. But, before considering the change, I'll change the strings to see if it holds the power of ezone a little. Now I'm using Lynx Tour and I'm going to change to Hyper-g.
