Profahoben_212reflect tech (or whatever moment calls it) where the sidecut matches the rocker
hot.pocketYou have the description correct, but the 107 Meridian sidecut does not match the rocker. The 117 Meridian has radius rocker (essentially the same as 4frnt's reflect tech) but the 107 Meridian didn't ski too well with the large 33m sidecut and was tightened up to 23m.
Either way, I'm about your build (6'2 155) and have skied the 181 and the 187 extensively. The 181 is a fun ski, but for guys our size the 187 is absolutely the way to go.
