Hey tennisbody,
hope all is well. I was very happy to see you defeat your slicing nemisis, but sad to see that the scores disappeared from the post. (Best weapon for a crafty slice is...). I like to be able to see the evidence (the score) that a tip works, plus you had included a little extra tip for everybody that was erased too. I guess you didn't want to give too much away to the rest of the world (the slicers might adjust and take their revenge) ha ha ha.
It should be noted here that tennisbody is an EXCEPTIONALLY strong guy. His muscular development is at least to the level of a state bodybuilding championship competitor, and I'm not talking about a short one, He's at least 6ft and makes any top 100 pro tennis player look like a twig (sorry Marat, you too). His Body fat is also exceptionally low, probably under 7%!
This may influence his ability to perform a rather unconventional technique consisently. More muscle in general will let you get away with more off balance weird stuff (he could be falling away from the shot and still knock the crap out of the ball). I'm guessing by fine tuning his technique he could top out at hitting around 100mph forehands!!!
If it works for you, go with it...
You may have trouble hitting the short low ball this way though (the one you have to move forward for) because the bent left leg may get in the way of the forward swinging racket.
Leaning at the waist/spine over that leg (to clear it with the swing) will put you more off balance and thus more vulnerable to your opponent. I don't know how many times this will come up in your matches, It may not be an issue.
I want to see you start entering some open tournaments and kicking butt!!!
With your great physical strength and hard work ethic (I put this guy through his paces and he kept up well), you clearly have some incredible potential!
