I've used the APD for about a year and a half after taking up the game again after a 18 year sabattical. Everything seemed to be going fine until the last month or so, but now my elbow is tight/tender after playing. This feeling isn't horrible the next day, but I still think I should consider some arm friendly alternatives. I play primarily doubles, but also play some singles. When I play singles, I generally play baseline with a semi western forehand and 2 handed backhand. So far, I have on my demo list the following: 1. Volkl Organix V1 midplus. My wife uses this racquet, and I've hit with it. Seems very arm friendly. 2. Donnay Formula. Any other suggestions would be great. Thanks in advance for suggestions.
