Hello all,  Longtime lurker, new poster.  My current ski driver/ski partner has one leg: His right. Nothing below the knee on the left, nor even a left thigh muscle.  We've been skiing together only this summer. At first he was reluctant to attempt the course, however, after one time he's now hooked. He can make cuts on both sides with confidence. My reason for posting is, any and all advice from those who have skied with or coached one legged skiers is requested. Clearly there are some balance issues that cannot be overcome. We are making progress, he's at 1 1/2 balls at 15 off, 28 mph. He's dieing to make 2 ball, his really off side. I've been trying to figure out how to help his overall weight distribution problem and was wondering if you think it makes sense to add some weight to where the back foot would normally be? Or just keep at it from a technique perspective.
