Bringing back an old thread. I only ever added a thin spacer to my RTP, between the binding and aluminum mounting plate but not sure if it was enough to really make a difference. Looking at some of the pro skier binding setups I notice that some, like Will Asher, use a Reflex/HO style front release with a RTP that looks to have no cushion (just plate with non-skid for the RTP). This got me curious how high off of the ski is the foot with a Reflex/HO style release binding? How much difference between front and rear does the non-skid only RTP result in?
