Replying to 2019 Kartel 108 Mount?

I've read a few threads pertaining to this already but I'm still torn between recommended and -3/-2.5 from center. Just picked up a pair of 186cm K108's this season and plan on using them all mtn but I still want to be able to spin, flip, butter, ski switch, etc with them. Im 6' and about 220lb for what its worth.
I currently have a pair of J allplays mounted at center for a 'park ski'. When i'm out of the park i still like to ski fairly spirited (lots of butters, natural jumps) as well as rip down the steeps and through the trees. Gonna be using them mostly East Coast as thats where I reside/go to college.

Can anyone add some input into the topic? Thanks NS!
