Replying to Center mount ski size?

I’m buying new skis. I’m 6’ (183cm) tall, 140 lb (yes I’m skinny I know). I’ve skied on 176 Armada AR7s for years since I was a teenager for some park some all mountain.

I’m getting a pair of On3P Magnus 90s. What size should I get? My current skis are 3/4 mounted so since these are going to be exclusively park skis I’m thinking 181 for a bit of extra length to balance out the center mount but I’m nervous it will be too long since I’m very light for my height.

I mostly do jumps and some rails, I throw a decent amount of 360s and 180s and like to do medium and some big jumps.

they have 176, 181, and 186. What do you guys think?
