Damn - I must be super heavy then.... In reality, I use the high friction side if I'm on my 9mm doubles and the ab is overhanging, super long and pretty steep, I want to stop to retrieve gear or if for some reason I'm not feeling so comfortable with it and want the extra control. Otherwise, I just go for the normal side. On my old, fat single rrope it was be the low friction side every time. It is nice to have the option though, and then it doesn't mattter if you're climbing on super new and slick skinny doubles or an old and furry single.
