Replying to ARV length advice

hey i'm planning on picking up the new ARV's this year but i wanted some advice from those who know on what size would be best for me. i think i'm kinda between the 175 and 185. i've ridden 180s before and 183s but were k2 which i know is a little notorious for riding a little shorter than they measure. the thing is that i've grown since then. maybe only an inch of height, but i weigh a good 190 now when back then i was more like 175. i'm stronger now because of that also, so, i'm in a little bit of a quandry. any advice is appreciated. thx.
