Replying to What size ski?

I am 6'1 (185 cm), 165lbs, almost 17 y/o. I ski 50/50 park/all-mountain. I am an advanced skier

looking at some Moment wildcat 101s, but I cant decide between the 184cm, and 190cm. I have heard they ski short, so I am leaning toward the 190s, but idk.
I have skied some faction prodigy 1.0s in 181cm since I was 5'10, and they felt a bit short last season.

also where should I mount the bindings? the factory recommended is -5, but im thinking around -2/3 for park
