I've been a long-time RS wearer, mostly because of the sizing/fit. The Small has always been a perfect fit, unlike almost every other short I've tried on - if they fit my hips, the waist was too small and it was a real struggle to pull them over my hips. I'm 125#, 5.5 with 36/37-inch hips & 28-in waist.

Tried on a 2012 RS model and could barely pull it on! The sizing definitely has changed. Plus there's been another price jump, despite the fact that these shorts are made in Canada. I was rather discouraged at the prospect of a major hit to my wallet and decided to try on the Evolution. I love everything about this short from the waistband fit to the fabric and it's $55 less than the RS! I don't see any noticeable difference other than the fabric's slightly denser than the RS. Also can't notice any difference in the chamois.

I was considering of a pair of LG Neo Powers (?) but the legs are too short on me - they're only available in 7" - so very unflattering on my 74-yr old legs. They do look great on the younger women I ride with.
