I ride nothing but plate bindings and hard boots (Burton Fire's that are all cracked to squat but still holding) in all conditions and all boards from Burners to Primes to a Frontier 185, Canyon 173, Burton Air 172 etc ad naseum infitum. In bumps, crud, pow, everything. Well I don't do parks and rails. I never let my edges touch anything but snow actually, no wood or other skiers or lift line loadies. Too much gear for sure. The point is you don't need to have two sets of boots.
Good luck with the boot fit.
