@BRY Thanks for the feedback Bruce, one point of note, in communication with Reflex, they said this:
"The Supershell is a bit more flexible than the classic models."
It's funny though, I put an RTP on my ski the other day and skied it for the first time in 25 years (in anticipation of the Reflex SS that was in the mail)...when I made an offside turn I fell right over like a noob! Felt like I was skiing on one (front) leg. Now I've got to consider the R-style back boot. Made me think though, is there something I'm doing style-wise that is deficient, or am I just not getting enough support out of the RTP? Honestly, I felt like there was nothing but a pad back there, there was no support whatsoever.
