My backhand is by far my most neglected stroke in my game. I have a solid serve and forehand.. but my backhand is really holding me back. For the longest time i used a weak slice that all i could really do is "pop it back in play." I've been experimenting with the two hander, one hander and trying the improve my slice but to no avail. My two hander feels awkward and i can only hit a decent shot when the ball is coming slowly and i can set up. My one hander has a lot more power and penetration and is definitly the more natural feeling stroke. But i have trouble developing topspin and often net it or hit it long. My slice isn't really a slice.. mostly because there is not a lot of backspin and it doesnt stay very low either. So my question is what do I do? At this point I'm just looking for a solid shot I can get back every time. I feel like the two hander might offer more in consistency.. but I can't seem to use it on the run whereas my one hander feels much more fluid and powerful but i just dont seem to be able to "spin it in" when i need to.
I can sympathize with your situation. It will eventually come to you if you work on it a lot. I agree with CaldwellYSR that if you're more comfortable with the onehander, then you might as well continue with that.
Personally, I use what I guess is basically a Continental grip for all backhand strokes (flat, slight topsping, slight undercut) except the extreme topspin where I think I adjust a little toward Eastern. And a closed stance on contact. For extreme topspin, my racket is coming from a bit lower and brushing up on the ball more.
The essentials to hitting consistent backhands are, imo, basically the same as hitting consistent forehands, ie., footwork-preparation-eyeing the ball all the way to contact-and follow through. The more I practiced these things (along with different grips) just hitting against the practice wall (trying to emulate certain pros), the more consistent my backhand became and the more confident I became regarding hitting out with it on the court.
You should post some videos so that people people here who can analyze strokes really well (which I'm not one of) can give you some pointers. It might shorten the time it takes for you to develop your backhand, and avoid some of the mistakes that trial-and-error learners like myself apparently had to make before things started to click.
