I disagree. The 3 piece design of burton and flux results in stripping. Any tweak and it skips ladder steps. I'm not saying it's bad, and can't be averted with careful pressure, but it's just a drawback of this design.
The Union design is perfected. They've profiled it so low there's no room for error. It's superior in hold and ratcheting. And the release is easy when you apply thumb pressure on the top and lift with the index finger simultaneously.
Your right, but only if a person knows specifically to do that. The binding instructions don't have anything about it, and when I first got them I was thinking how the balls do I release this?
Of course a second later I realized the easiest way to do it, but there are some people who lack common sense. I've seen several guys in the lift lines who bitch about it but when they try to take off the toe strap, they just try to do it only using their index finger. I have to explain to them to also use their thumb, then they stop bitching about it.
They could release it like that if Union had release levers on their toe ratchets but because of the look, I assume, they don't. This is the only reason I could think of for this- there's definitely enough room to have a lever like there is on the ankle ratchet. I think this is a stupid excuse, if that is the reason. Sacrificing functionality for a better looking product was a mistake here.
