Just a heads up, but as far as I see it, there is no such thing as a "proper" grip. There's a range of acceptable variation. If you already have a decent forehand, I see no reason to change it unless a qualified coach or knowledgeable person told you to.
oh yeah most defintely. no grip is proper but you could say they are considered proper. although after learning the grips i've found that im more consistent with a full western for my forehand.
