Hey guys, I'm a 5.0 player who grew up using the Dunlop 200g (black & silver), but used the Head Ti Radical all during college because I was having some elbow and shoulder issues and the Head was much easier to swing. I've recently gone back to the Dunlop M-Fil 200 (16x19, little lighter) with no problems with weight or my elbow or shoulder. I recently order a Yonex RDis 100 mid because I just love the little weightier feel and the heavier racquets really help my serve a lot. I tried Using the K95 for about a month and the elbow issues came back while using that racquet and were gone as soon as I stopped. I'm concerned this may happen with the Yonex as the weight is comparable, although the swingweight of the 2 are vastly different. Has anyone hit with the Yonex RDis mid and got a good feel for the swingweight or if it tires your arm out and produces a lot of vibration? Also, any other opionions are very welcome. Thanks.
