Re: Does size matter...
"I've just never seen a 95 pound girl apply a iron grip sankyo."
I think it has less to do with strength than with hand size. I'm consideraby larger than 95 lbs, but all of the largest men I've ever met train in my dojo. Some of them have wrists as big as my arms, and I flat out can't get my hands (yet? I hope) into the right positions to do some wrist locks, especially nikkyo, on them.
