At 2007 Worlds in Stutgartt Germany, it appeared that the chinese women were wearing "home made" grips in witch consisted of foam and some athletic tape. I can't answer for sure, but before they would go up on the UB they appeared to be pulling the tape tighter that was tied around their wrists. I don't know that would recomend it to any body I coach (those being boys) but it appeared to work alright for them.
I would get suggestions from your coach. He or she maybe would like you to wear a certain type.
