thanks for the feedback guys,
just worried that i'll wreck a pair of skis if i mount them centred if its not recommended. looking for something for mainly big air and nailing pistes and the occational bit of jibbing, basically what the line step up is described as!
its such a hard decision to make! really want something durable, there are so many factors to consider! was looking at the AR7s but they arent recommended to be centred and as you guys say, phycologically this puts me off!
