Replying to ARMADA JJ 2.0 SIZE HELP!!!!???!!!!

Hey, I am looking into getting the ARMADA JJ 2.0 but I can't decided between the 175 and the 185? I am about 5'10'' and weight 210-220LBs. I want something that i can use in the trees and be agile and able to do nose butters and not have to much ski but still want float for when it snows.

I NEED SOME HELP PLEASE!!!!

II ski the LINE CHRONIC in a 171 right now. never skied anything over 175 and just don't know about the 185 length and there is no place to demo these on the east coast!
