Replying to Salomon Shift durability/downhill confidence

So I just picked up a pair of k2 marksman and I’m looking to start getting into touring/want to have the option to tour a few times a year and need to decide on bindings. I ski park primarily, but won’t use these on rails ever as I want this setup for the few pow/all mountain days I get each year on the east coast, as well as tuckermans in the spring. Was hoping to get some input from people that have been skiing the shift for a little while now to see how durable it is/holds up to a year or so of abuse etc. Also how confident they feel in it’s retaining/release ability when skiing aggressively downhill including cliff drops or steep stuff like Tucks
