Replying to How long should my Park Skis be?

I've read all kinds of conflicting information online.

My height is 6'2 and I weigh 125kg (275 Pounds in the USA, I'm a heavy bastard but I send it hard haha)

Spent Winter Down Under on 176cm Atomic Punx, which suit Aus/ NZ conditions for me, but now I'm looking for something with a wider waist and all-mountain setup for an upcoming trip to Austria.

Most likely going to go with Faction CT 2.0 and I can't decide between 184 and 188. What do yall reckon? How do longer skis affect Jibs and Landing Jumps etc. Do you think it's easier or harder with a longer ski? Considering my height and weight lol

I traditionally have prefered a shorter ski so I can whip around alot easier on the mountain, but this may not be so beneficial in the deeper snow, that we don't really get over here in Aus

Cheers
