Capo is on a higher level than Castelli and Louis Garneau, the fabrics and chammys are much higher quality. The Capo Dorato (Padrone, Martello, GS Capo Giro Kit, custom team kits, etc) on up has an excellent chammy that is just as good as Assos and Rapha IMO. Try one of the higher end Capo kits out (which means you'll probably have to buy it and drop at least $300 sorry) and see if you don't like it more than your Assos or Rapha.
