>>2846560if you're still lurking anon, look into classic telemark stuff... originally the gear was almost indistinguishable from what you're describing. You can find somewhat heavier, more rigid 3-pin bindings, and while it's not heel "locking" per se they will also accept removable cables which tighten your boot down into the ski even more. I don't know where you like to go but it sounds similar to me, I use 3-pin and have regular nordic boots as well as some asolo tele boots I got off ebay for ~$50. The rigidity of the tele boots alone had me going down logging roads I was crashing on before, and adding more of a "tele turn" and some pole planting got me carving which on edgeless xc skis makes me feel like a boss (I can do some regular alpine already)
I can't actually rec picrel book since I just ordered it but maybe check it out.
