Hi. I'm a 4.0 high school team player and currently using mild semi-western grip on my forehand. I'm thinking of modifying grip a little bit because extreme semi-western grip gives me more topspin and control. I know how to hit with extreme semi-western grip and have been practicing it. I just want to use extreme semi-western because of the control I get, and it feels like extreme version fits better to me. However, I've read an article talking about the disadvantage of extreme semi-western grip limiting the level of play for the future. So, I just want to know if it is a bad idea to go from mild semi-western grip to extreme semi-western grip which gives me more control.
