Replying to I'm such a binding n00b...

OK, so when I comes to bindings, I have no clue. I'm wondering if any of you experts could help me out (cobra_commander, Silence, EmbracedByLeaves come to mind).

So, basically, I know that most bindings are essentially the same. I just don't know which ones.

For example, Look PX12 vs. Rossi Axial 120?

I have 06/07 ARVs with Rossi Axial 2 120 bindings on them. I'm interested in picking up Surface Live Life's to be my tree/pow ski. Should I pick up another pair of Rossi Axial's? Or would they be too heavy?

I'd also like to just gain knowledge on the subject, so anybody's input is more than welcome.
