Tiger paws and grips are two very different things. Grips do not keep hands from hurting...they are equipment used to enhance performance.Well, it sounds like I am in the minority here on my opinion.
A little background though...my daughter did T&T for a couple of years. Practice consisted of about an hour of constant tumbling. Her pass was round off 7 bhs. So, her wrists really hurt. She actually broke one of them while doing a bhs. No, her wrist were not turned out...her form was good. She wore a cast for 6 weeks, followed up with 3 mos of PT. The PT helped some, but she really needs the tiger paws and the therapist and doctor agreed that she needed the support.
I had also heard that the tiger paws will make the wrist weaker, but it is what she needs to be able to do gymnastics. She loves them, and they work for her. I guess gymnasts don't really need grips either, but most use them to help them out with their grip on bars. Maybe if they never used the grips, they would have no trouble hanging onto the bar as they would have more grip strength? Not sure...just a thought.
