I have always played with the Microgel Extreme with the grip size at 4 3/8. It's too small so I've always added 2 overgrips to bulk it up. Would it make more sense to just buy the racquet in a bigger grip size? I've heard to always stick with what you've been doing (stick with the 3/8 and add overgrips) since thats what i'm accustomed to, but I was curious if anyone else had a different opinion. Thanks!
