Haha didn't you just say before that you really wished the Unions had canting? I would think for a rider like yourself with previous injuries that the canting would help relieve the lower body stress for you.
Oh I def wish they did. It something all bindings should prob have. But it's def not a deal breaker.
It's like boots that ergonomically lean inward. Not all boots do, and it's not something you really notice, but you might if you came from a boot that did to a boot that didn't. It's just something you'd think all boots would incorporate into the design.
