I don't really understand. I've adjusted 6 or 7 different bindings a couple of times each. 01 and 03 Ultras, 02 and 03 parks, 02 belmonts, 01 splits, and some old 1942 bindings. None of them were real hard. I've had a little trouble a couple of times, but nothing really hard. But then again i got some serious skeeeeeillls!
