I don't have them but a guy I ride with uses them and LOVES them. He has the stiff pair and weighs around 100kg and rides an SG Full Carve 180 with SG hard plate and F2 bindings as his daily.
I'm seriously considering a pair but with my UPZ fitting perfectly and with a couple of new buckles to stop rubbing, rcr cuffs, palau liners, rear intec heel ... it's a tough pill to swallow. Kind of wish I still had my ill fitting Deeluxes so I have an excuse to swap...
