@jgills88I think I’m understanding what some older threads had you thinking. When people running, let’s say Wiley’s, have asked if they should buy a new ski and put a Reflex setup on it EVERYONE jumps in saying NO, stick with your old boots when you go to a new ski. It’s really a function of keeping it to one variable. The ski will be, as @Hortonsaid, “a blank canvas”. You have no idea what the ski wants; does it like a lot of front foot pressure in the pre-turn, will it eat your lunch if you get tail heavy on the onside, etc., etc. If you get a TOTALLY different boot system, the inputs that you know work on the old boots may do something wildly different on the new setup.
I stick to my original post at this point now. New boots on old ski, you’re still going to have to find the “right” boot placement, then go looking at fin. I MIGHT even consider taking the fin back to stock when I change to a very different boot... that one I can be pretty hard-headed on though and stay on old fin settings too long
