No problem with my Lepera Barebones so far. It's one of the thinest solo seat available but I find it quite comfy for a few hours at a time unlike some others have reviewed.
Just shy of 10k miles on my Brawler in a little over a year. Once it breaks in it's fine. there is no back support though. No other seat puts you down and back as far as the Brawler. I'm 6'1 ~200lbs. I would like a backrest though. tempted to get the C&C just for that fact.
+1 C&C Solo w/ backrest. Just wish I'd stayed away from the gel and stitching.
If your scoot sits in the sun for awhile the gel will stay hot for a long, long time (and I mean l-o-n-g) and so will your a$$.
Smooth leather is more comfy than stitches or texture. Not as pretty, but much more comfortable. Gonna get mine changed to smooth/no gel real soon.
