Re: What is the best forehand grip? Can anyone help?
If you feel comfortable with an Eastern grip that's probably the best way to go. I tend to float a little towards semi-western at times (esp with hitting high balls) but is definitely an Eastern grip. Once you're used to the Eastern, you can actually put a little time into practicing with Continental as well as Semi-Western. Doing this can help you develop more strength on your hitting arm.
There are a couple of good, free websites for the basic mechanics of groundies. Fuzzy Yellow Balls just to name one of them.
