Otherwise for all mountain I, personally, use a 21/-12. It is a little bit more aggressive on both sides, but that is just what I like when I am bombing trails and fooling around on rollers. If you're looking for a new stance just get a screw driver and f*ck around for a while
it's what i've done for all of my stances
