Alright, I hate binding comparison threads as much as the last guy, but these two systems have really caught my eye and I'm trying to decide before they release in the fall. If anyone has firsthand knowledge that they want to contribute on either platform, it would be greatly appreciated!
The bindings:
Atomic/Salomon Shift

About me:
I've done a bit of research, and these two systems seem like the best of both worlds for binding retention on the downhill and weight saving on the uphill. I am using Atomic Hawx Utlra XTD 130 boots that have tech inserts and WTR soles, so both the Shift and new Pivot should be compatible. I typically run my DIN at around 11, and tend to ski more aggressive lines with switch landings and carves mixed in. Planning on mounting whatever I purchase onto a pair of Moment Bibby/Wildcat Tours in a 190.
