Calimero377: The title of this thread is "Thoughts on Steffi's backhand" which is what I addressed in my post. I mentioned the slice backhand, the flat-drive and the topspin in my reply. If you wish to start another thread and only discuss slice backhands then knock yourself out - no one's gonna stop you.
However, if you choose to disrespect any and all players' achievements that came before Steffi (as is characteristic of you) then that's your perogitive, but I'm sorry, I happen to hold tennis historians (Ted Tinling for one) and legendary players (such as Alice Marble and BJK) opinions on Betz and others higher than your own - nothing personal! And no, I never saw Betz's backhand live, but neither have I personally witnessed Pancho Gonzales's serve. Does that mean it shouldn't be discussed or considered at all in such forums? I thought this board was one dedicated to tennis history? Oddly, it seems history for you starts at 1986 and ends about thirteen yrs later. Sorry but if that's actually the case, quite a few of us on this board might certainly disagree!
