question about the werrd two fat ladies yoyo

i really want to purchase these but it seems there out of stock everywhere the only version left is the groovy, now i really dont grind or anything like that. I really wanted the polished but will it really make a difference if a got the groovy, what would be the difference? Please help me out because id like to purchase one tonight thx.

It Just Has Grooves like a P2. Thats the only difference.
