Based on your height, I would say go with the 185cm. If you are a really aggressive skier, than you may even consider the AKJJ 195cm. Im 6' 165lbs and I really like the 185cm skis.

Are your JJ 185's still for sale?

I have the same exact ski as kellner12113072 and I think the skis are a kick in the pants. I only dislike their busted up crud ability, they get very nervous, bouncy, like I need some shock absorbers in my knees. I ski them when its freshies and when its firmpack, I dont like them in between. Crazy I know. I have owned Obsethed's, Mantras, Prophet 98's, but the JJ just frustrates my in the crud. I'm 6' 1" 185lbs and ski the 186cm and they feel like the could be longer on powder days. Excellent carving ski, they rail! I'm trying an experience 98 this year so my JJ's could possibly be up for sale mid season. At least they're easy to sell.
