Replying to Thumb Braces for Skiers Thumb

Hey I have been researching this for a while, and I haven't found much about people who wear thumb braces to stop skiers thumb. I have broken each of my thumbs 5-7 times per season for at least the last 5 years. I'm sick of it honestly, and I've been researching braces a bit. Here's one that I found called the Bio Skin thumb spica:

It seems pretty good, but I'm gonna ask my physical therapist about it tomorrow. I just want to see if anyone's used anything like it. I found this thread from 2007 that has a very sick brace, but apparently they are hand made by some unknown lady in Park City. Here's the thread:

Maybe someone can help me out? I'm trying to plan in advance not to screw my thumbs up again. And I forgot to mention, I have used my poles holding them correctly with the strap, and with no straps, I have also tried many different kinds of grips, etc... They all fail. Maybe someone can help me out?
