Bottom line: For this skier, these bindings offer the best balance between usability, weight, cost, and safety for a dedicated backcountry touring setup.
In addition to the Speed Radicals, I've ridden the Speed Turns and Radical ST 2.0 and 1.0s. I've sold all of those other bindings and now have these on my three touring setups.
Stepping in and locking the toe are easier without the rotating toe offered on on more expensive Dynafit Radical bindings.
Going brakeless saves weight and improves speed/usa...
