rickson, the ball doesn't pop up at all. i tend to hit my backhands a bit flatter though.
gmlasam, that's correct, my right hand is in an eastern forehand grip while my left hand is in a continental grip. one drill that a lot of people use is to hit opposite handed forehands, this really helped me out as well (i learned this on these boards). if you go down a few posts, i posted some videos of me hitting a couple of backhands.
