Replying to Volkl Mounting

Boys,

Picked up a pair of 186 Volkl One's as my inbound, jibby, freeride ski for this year.

Currently struggling with where to mount. Want to go 2 cm back of true center (which I think is +8, not sure though) but the Volkl reps are saying the core isnt reinforced that forward and the bindings will be more prone to ripping out, so are advising +5 at a max. I'm use to a fair amount of tail on my skis and don't know how it will perform.

Anyone had any experience on the Volkl One's or Two's and care to share where you mounted and how you found them?

Cheers.
