Thinking of purchasing a slightly OS racket for my aged eyes, I also have very sensitive arm/wrist. Don't want those low power ones since I can use some extra power from the racket. It seems that the Ezone 105 is a good fit. Planning to add lead on the loop and handler to bring it to around 11.3 oz 320sw. Will that play like a more forgiving and slightly more powerful Ezone 100? For those of you played this racket before, do you feel it is more arm-friendly than the Ezone 100? Does it really feel more flexible than Ezone 100 (Ra 66 vs 69 by numbers)? Any feedback on this racket is appreciated, or please tell me if there is other good choices. Thanks in advance.
