So I've been on a Donek Metal FC (somewhere in the 170-180 range, not sure for certain) and a Volkl Renntiger. The Donek was spectacular, if I hadn't already bought new skis like 2 months before I probably would have bought one already. The Renntiger is good, but its like a 165 and it feel a bit short to me. So that's what I've been on.
I don't know exactly what the binding angles were, but it was pretty steep (50-60*) and that seemed to work great; not coming from softboots, I don't have any habits to break from low stance angles. Honestly, it felt surprisingly natural. I found regular snowboarding to be *way* harder when I tried that a couple years back. As for cant, no idea; I had people way more knowledgeable than me helping me get set up, so I just went with whatever they said lol.
Boots are mondo 28.5, with I believe a 309mm sole.
