I use mostly the lean method. I think anyway. Never really thought about it I just do it. After a little more time I think it makes my presses more in control but not as exaggerated. My nose press is now just gets the tail a couple inches of the ground but I find I can steer and hold the sweet spot a lot better.
I really do like those bindings. They seem to really help with fatigue. Tight woods are exhausting and being able to sneak in a few extra turns before your legs get destroyed is very helpful.
My core shot was actually not jibbing something it was just from going somewhere that snow doesn't stick as well as I would like it too.
I was somewhere along the top ridge here
