@303Skier have you seen anyone with the new HO system? It sounds like they have worked out the bugs.
@Ajskier I had the same concern when I purchased my reflex system w/r-style rear binder. I also wanted a 2 feet in 2 feet out release system; due to the fact, I also twisted my knee during an OTF when my front foot stayed in (prior to the buying the reflex). But with all of the bad news with the HO system I didn't want to chance them. I ended up buying the Reflex. Not trying to sway you to Reflex, I'm just telling you my story. I would try to get advice from someone using the new HO system. It seems to me they have fixed some of the major problems.
I also looked into the FM Quattro's, which seems like a great system, but didn't like that I would have to drill addition inserts into my ski. Not that there is anything wrong with adding inserts, I just didn't want to drill in my new ski. Also I didn't like that they are aided by velcro under the bindings.
