Replying to Ski length for park - 5'10" 150lbs

So I know the searchbar 185 length is really hot right now, but I'm looking for some legit substantiated responses.

Last time I was on NS (about 4 years ago) dins were the major dick-measuring contest, and it looks like ski length is that now. So, I'd like some info from folks around my height and weight using skis for a similar purpose to let me know why they like the length they ski.

I'll be using these skis for park. Rails, jumps under 50ft and early/ late season urban and messing around with friends. I'm 5'10" and about 150lbs. I'm 23 and ski pretty laid back. I'm an expert all-mountain but more intermediate in the park. I run my dins around 8. I've tended towards the the mid to low 170 length range in the past. More info to help out gear sticklers, I'm Canadian, have blue eyes and I sometimes take long walks on the beach, only during sunsets, cuz that shit straight tears me up, son.

Big ups and +k for helpful responses. Good to be back NS! Been in Nova Scotia for too long, about to go into some serious debt skiing Alberta.
