I bought my first pair of assos a couple of months ago. They work. Had carnaris before that and the chamois was a nice, soothing bed of razorblades. Moved on to Garneaus (some performance exclusive model, about 80 or 100 bucks) I loved them but after a year the chamois flattened to nothing.
Now I am on assos. All I can say is they work. I probably won't try anything else and stick with them since they do their job and I don't have the money to fart around. I'd try maap or rapha but not really a fan of the logos on my thigh. The purple band is rough enough on my assos.
I just wish someone can honestly tell me the difference between the models. I have the equipe s7, curious how those match up to the other models. Their website gives me a headache.
One cool thing though, once I tried them on for the first time it oddly shaped my body in the chiseled hunk of flesh on their website, the same was drinking a dos eqis turns me into a chick magnet.
