How much you plan on riding park. I have bridges i mounted 1.5 cms back from true center and they slay all mountain and ski fairly well switch including switch landings. but i have some walls true center for park so i hardly ever ride the bridges in park
My brother mounted them back and regrets it. My friend mounted them on true center. If I were you and only skied a little park I would mount them at core center
thats about what i ride on mine, and they perform great on the true center line. the true center line is not really "true center" its far back enough so you still rip the mtn
