Thanks everybody for the feedback. I hated to cause a deviation from the original purpose of the thread but I got what I was looking for so thanks.
Leo, thanks for the offer of trying out one of your Flow bindings for free, but I think I'd need an XL. I wear a 15 boot.
I think I am probably going to lean away from the M-9s just because I think that they may feel too soft for me. The RS model is out of my price range; the ATs are at the top of it as it stands. I just need to make the decision whether to bite the bullet and order them or stick with my Missions for the rest of the season. It's just now that I'm starting to ride a bit faster and turn more dynamically, I worry about these holding up considering my size.
