ummm, tough call on the mounting point, I had mine at center, they were dope in the park, and ok outside the park. -2.5 is recommended by Armada, I'd go a little closer to center (either dead center or -1.5) if you're doing a lot of park (say center if 90%-100% park or -1.5 if 75%-89% park, go with -2.5 if anything less than 75% park). And yeah, it's one of the most fun skis I've ever ridden, I personally don't like soft skis like Lines, cause I can't get a good edge hold in the ice, but this ski was awesome, very fun to ski and I was able to hold an edge in the ice.
