Replying to Powder skis

I'm 6'4" 160lbs. I'm looking for a pow ski to play around on in pow, do some steeps with in pow, bc booters, groomers when going back to the chair and the occasional park run for when i feel like fucking around. I'm considering the 189 hellbents cause of the length but I'm afraid they might be too soft. I have 185 arv's now and they feel pretty soft and a bit short because I got them mounted near the center but i dont mind it. I would go with JJ's but they're too short for me.

AND Should I mount with fks or jesters?
