From: Chuck on 10 Feb 2008 17:40 I was hoping to get more comments here as to what people have tried. I have used a locking pin for ten years and I guess I was really curious about the amputees using a suction system. Oh well........

I think pin and lock or suction both have their advantages,comes down to personal preference and what's comfortable.I was lucky enough to have a prosthetist that tried both to find what worked.
