Replying to Moment Bibby 186 or 190s???

Ok so, I have my heart set on moment bibbys. Problem is that i don't know which size to get.

The 186s are softer overall, more sidecut and half camber. They are basically a BC jib ski like the JJs.

he 190s are apparently much stiffer, designed for big mountain charging and cliff stomping. They have a long effective edge for a pow ski and significant camber and larger turn radius.

Im 5'11 and 165 pounds.

Im used to stiff skis and that is generally what i like to ski for the stability in variable snow conditions. What im concerned about is the length and stiffness of the 190s. I do ski a lot of TIGHT trees and chutes and im just not 100% sure i can handle that much ski.

now i know these things are rockered so they ski short but im just curious to see what some experienced people have to say.

Thanks.
