I have a head YOUTEK speed 16x19 thats a 3/8th grip with a prince quickzorb overgrip. Tennis season is starting in my HS and I'm looking for a second racket in case I snap in the middle of a match. I want to buy the same racket on tennis warehouse but the only available grip is 1/2 and 5/8. Does anyone own this racket and felt any difference between these two sizes? 3/8 and 1/2? Also, yes, I did ask tennis warehouse when they were going to restock but no reply.
