I've seen video of Steve using a harness with his littlest... Both of them on boards...I don't know how he did it! It may not be fun for them, but you've got to get them on easier terrain otherwise you are never going to break them out of that "style". Would you consider signing them up for lessons with a pro? They may be more willing to try something different than they would with you. I got so frustrated with my daughter going up the rope tow, that I had to ask another instructor to take her. Same thing with the chair lift the first time. My daughter has always been pretty slow and cautious though. The crash and burn style you mentioned is exactly why I don't think real little kids should be on boards anyway. Yes, there are always exceptions, but most lack fine motor skills. Are your girls pretty athletic? Most ski areas will take kids on boards by age 10 for lessons. I taught a lesson to a girl last year that was probably somewhere in the 8 to 10 range. She, too, preferred heel sides. Once we discovered her Burton boots with the Velcro and the grow system were not snug on her leg and managed to get them tighter, she did much better.
