^^ yah i was thinking the exact same thing, your effective edge on a normal groomer is gonna be like maybe 8 or 9 inches...also, when you say "5 stage rocker" do you just mean you cracked them at 5 different points on the way up the length of the ski? if so, those things are gonna collapse the second you put any sort of weight on them, cause you basically just created 5 huge hinges at the tip and tail inside the core of your skis...
