Those reviews are right. I'll NEVER use a pair of Technine bindings again. They might have improved recently(probably not) but from my past experience... worst bindings ever! (Ali Goulet pro model, MFM pro model). Man, I don't even want to talk about this anymore, they are so brutal it puts me in a bad mood.
Top bindings companies these days (not in any order): Rome, Burton, Flux, Ride, K2
You might even throw Union & Salomon in there.
Look at the stiffest 2-3 models from each of those companies, and forget the other models (judging by your weight, enough experience, and past gear).
Going from a 5 year old setup to a brand new setup - you're going to feel a world of difference right away, in a good way. Necessary upgrade. Right on!
I don't see anything mentioned about new boots though... (you need them)
