first off, you need to center mount invaders, that's what they're made for. Secondly, unless you're skiing hardpack through the tress wich i highly doubt your not, they're gonna be hard to handle. Try going with something that you can mount back a little further such as the Armada AR6 or the Salomon Suspect. The suspect would be your best bet if you're looking for something to tae you into the trees too.
