First season skiing park and I needed a pair of thrashers. Got a pair of 2009 armada arv's for 25 bucks with perfect bases. I was pretty stoked about getting them that I didn't notice that they'd been mounted twice. I can mount a rossi binding in the same holes but its not a true center mount. I just want to buy some lower end bindings and true center mount them. Should I just go for a third mount? Do I need true center? Are rossi bindings even good for park?
