I have a question regarding holes pattern on 154 size and stance options. The reason why I'm asking is because I will use it with burton cartel re:flex bindings which as all of reflex bindings have limited (to one) stance options in their discs. In this case my only stance options are limited to those coming from board.
Hey Lucas I don't think you have anything to worry about with the Cartel re;flex.
You still have the ability to adjust stance angles with the disc in the binding, and the insert pattern (I'm pretty sure the Proto uses standard 4x2 6-pack insert pattern) on the snowboard allows you to adjust the stance width. This is no different than any other (non-Burton ICS) snowboard/binding setup.
So you are definitely not limited to "only one" stance option.
