http://www.ultimatebalance.com/art2_tennisone.html pretty sure this site is trying to sell you something (in all seriousness, i didn't investigate what it is)..... but very, very good videos of borg, mcenroe and federer forehand and in-depth article, all for free without no registration required. what i am curious about is this: what grip is federer using on his forehand??? i thought he's between eastern and SW, but his stance is fairly open hitting this.... trying to improve my game, and always thought that western = open stance, eastern = closed stance, SW = semi-open..... is this still correct??? or, do pro's use technique differently than us? due to flexibility, amongst other things? also, can't believe that mcenroe gets enough power from that forehand, although i know he wasn't baseliner at all. borg video is fascinating... so solid.
