I just returned from MY LBS, where I tried on both the Evolution and the RS. Considering the price difference I really, really, really wanted to like the Evolution... The RS, however, felt much better and as I always have a small muffin top regardless of the type of waistband, I went with the RS. Hopefully THESE won't get too large for me, I don't know what I will do if that happens. This gives me one pair of PI drop-tail bibs that fit me well, and the RS. I can live with two pair of shorts I am really looking forward to trying these out - hopefully this weekend if weather permits!
