I am wanting to get a Switchback, but am curious about which one to get. After reading through a lot of the threads here, I get the impression that people are gravitating toward the 1.9 dbl. I may be wrong, but that's the way it seems.

I know with the WBBB, I thought the 1.1dbl was more comfortable that the 1.7dbl, and most people seem to prefer the lay of the lightest fabric they can as long as they're within the weight limit of the fabric.
Does the same hold true for the Switchback, or does the different, flatter lay change that for the SB?

I am 6' and 165 lbs. What is everyone close to my size using?
