i would say jester because of its din versatility over the px12, expecially on a more bc oriented ski. the px12 is great proven binding, some people disliked the px heel compared to the pivot heel, but generally well liked. the only thing is limited din compared to the jester, but if the px12 still gives you room to bump up your din one or two without hitting 12 then id say either or...(personally im hoping to get a pair of jesters next year to try out. they look pretty awesome, especially for a powder/bc ski because of the wider platform)
i would try to stay away from the tyrolias and i havent really heard anything about the mojo's.
