They'd be aight. Honestly, adds weight, can break, and is finicky with bindings, esp. PX series.
Butttt! They can get you to unimaginable powder! Touring is amazing, like, wow.
IMO, if you wanna tour, and you get trekkers, you'll end up falling into a spiral deathtrap of money thrown out for better bindings and boots, etc. I would sell what binders you got and spend an extra $100 or so for dukes or freeride pluses, depending on how much touring you'll be doing. You be spending $100 or so for the trekkers anyway, so save time.
Either way, have funnnnnnnn!
