The BD O2 is a great stable binding for the resort. I like the fill of it and the stability that it provides. I'm riding them with Scarpa T2x which is great for the resort but not so hot for touring. If you need touring capabilities go with the 01 or perhaps the Voile Hardwires. One thing that bugs me about the binding is that the cartridges rotate throughout the day. I have to twist them every now and again to keep the flex stiff. All in all, I'm a BD person and think they make great high quality gear.
