Shreditor 92 Mounting position.

Hello!

I just bought Shredditor 169 92mm to ski on the East coast.
I moslty ski tremblant. Wich means that on powder day/nice condition I'll lap the park in the afternoon, but I get there at first chair and lap the trails all morning. 1-2 times a week

I also have a ski pass in a 100% park mountain (MSB). 1-2 times a week

I used to ski K2 Domain and been skiing center since 10 years.
I have K2 Hell Bent 169 (Shorties) witch are mount -2.5 from true center.
I feel I don't have much tail there, for park skiing it seems not enough!
However in the trees with 2cm of snow my domain really sucked being centered, so it's not a possibility! But also, the center to traditionnal was only 5cm(if I remember well) on the hellbent. It's around 7,5 on the Shreditor.

I never tried em, so I don't really know how they feel for real!

So where should I mount them?
50% park 50% trails doing Mostly side of trails, woods, ( kind of short radius) and some hardpack.

I ski switch also quite a lot freeriding, tremblant is quite flat in some parts and I love to pop high speed 180s(lower speed 360) and tail/nose butters 360s on bumps.

In the park, I usually do 20-30feet jumps doing tricks. I'm a huge jibber, I hit a lot of rails and love doing presses, my fav trick is doing a noseblunt on a street set-up.

I'm 5'6'' and weight around 175-180 pounds

-1, -1.5, -2, -2.5 or more? (from core center)

Also say why!
