I notice that as well. I think it falls along the lines of “you marry your bindings , you date your ski.” I’ve seen tons of skiers switch skies on a regular basis while still using their tried and true old school duct taped, bolted , glued, zip tied bindings. I’ve played around a bit with different set ups and skis come and go.. I always end up on my same bindings. That’s my theory anyway. That and the contactless bindings have only been out a short time. Most pros are still using classic reflex set ups.
