Getting a new setup. Got the boots (Ride Insano size 9.5) and have the board narrowed to 3: NS Cobra (most likely), Lib Lando, Jones Mountain Twin. I guess I'm a freerider, but I don't really bomb at high speed or do any crazy chutes/big mountain stuff. Mainly groomers, glades, and searching for powder in bounds. No park, no tricks, no switch. 95% of my riding is in Washington state/Whistler, so heavy, chunky snow most of the time.
Sounds like I'm going to need a moderate to stiff flexing binding. I handled some in the shop and can really see what people mean about the Union toe strap not being as "smooth" as the others.
It seems like decent options would be:
Cartel or Targas (only two bindings on your list I've had experience with). My 390's, while a fun solid binding, were a little too soft for pure freeriding.
