Replying to 17/18 ON3P Wrenegade 108 Mounting Point?

What’s good Newschoolers.

Today I just picked up a pair of 189 ON3P 108 wrens that I’m going to mount up with a pair of pivot 18s. Recommended is -9cm from center, I also ski switch a lot, not sure where to go here, I was thinking maybe -6?. I’m 6 foot 180 lbs, will be using these as a bridger bowl daily freeride charger (will ski switch a decent amount). Lmk what y’all think, and if anyone has experience with the ski please chime in. Super excited to ride these and complete the quiver.
