I was on a hand splinting course this weekend. The materials we were using were fantastic. They were really easy to use and had 100% memory so if you were unhappy with the result all you had to do was stick the splint back into the water bath and it reverted back to a plain sheet to start again. The materials were also very light but once set were very supportive. We mainly used Proform plus, orfit and orfi lite all availabe from promedics. Good Luck
