After finally committing to AT this year in the Alps, I did an ungodly amount of research on these guys. If you want to save weight and have a dedicated boot for AT, go with Tech bindings. They are killer for the hike. However, if you are just dabbling, The Dukes, Tyrolia Adrenalin's, and maybe the Atomic Tracker 16's will be your best bet If you don't want to pony up for boots with Pin inserts. Weight is kind of the big thing here. Something with a little more plastic will be lighter, (Obviously) but I've been a big fan of metal. I don't mind a little bit heavier binding if it means more stability and toughness, hence the reason I went with the Atomic Tracker's. Marker bindings are sweet, so if you've already put hands on, go for it. Listen to Harry though, I did a little bit of lurking on his input, and it definitely made an impact on my decisions. Good luck and welcome to the world of sweating for like 4 turns.
