Frist if anyone has a old trick release laying around I'm interested in finding one.

Now for the creative minds..... our youngest daughter was born without four fingers on her left hand. She has been skiing and boarding but as she progresses and getting bigger it is getting harder for her with only one hand to hold the rope. We have been using a small piece of rope tied to the handle so she can pinch it with her thumb and palm, it does work for her but its not the best. Most other things we have found raps her wrist and hooks or grabs the handle. But everyone can see the problem with these options (need a trick release) and if she falls and I drag her I'm afraid she give up.

I know many of you have been around the sport for years and seen many things. Has anyone seen anything that might be helpful? Or any creative mind out there with any idea?
Thanks, Wes
