UNION Atlas Snowboard-Bindung

I haven't ridden these yet but just bought them - looks like an excellent aggressive all-mountain freeride binding but the dial mechanism for forward lean seems like a fundamental design flaw as it spins very easily and doesn't lock into place, so I'll constantly have to check if it's still in the right place or has been knocked from a fall, brushing against something etc. Very strange that Union approved this design given how loose the dial is after a few turns of the dial to engage forward lean. It also doesn't have notches or markings so you need to count how many spins on the dial to match both, rather than showing F1, F2 etc. on Burton bindings for example. I am returning them just because of this forward lean mechansim and going for the Burton Cartel X instead. Would appreciate any thoughts from others on this!
