Agree w/you Denise in that I've used the same Smith Sliders for a few years and like them lots. I have been using them primarily off the bike lately though (as in driving or walking), as last year I got a pair of Rudy Project Rydon glasses with additional lenses (pricey, so I wouldn't have gotten them for myself, so they were a lovely present!). The Rydon model is noted for smaller faces and so I've been using them most often for riding as, even though the Smith Sliders fit me pretty well, there isn't even a bit o' slippage with these.
I had a pair of the Performance Athena also a few years ago, but I like having the extra lens options as it helps on early morning/almost dark commutes or overcast days to have them handy.
