We taught my grandson(now 7yo) to run the slalom course on a trick ski with a small fin added to the back. He is running into 28off @ 15.5. We can't even get him to ride the new HO slalom ski, though it is obviously time to change. He also has a smaller trick ski for tricking on and set a new PB last weekend in tricks. You have to keep the kids excited about progressing and moving forward. Having other kids around to ski with is a big plus! BTW, like his mother, he has learned to ski using my releasable binding system. And I have a box full of new size 2, 4, & 6 super shell boots. If you are looking for those sizes please message me.
