these seats are not even in the same category as a Tobin.. (having riden both, for touring, I prefer the wider firmer saddle of the Corbin by far) The Tobin is comfy but does not offer the same level of seat support and tends to wear on the back side after a couple hundred miles. Still better than stock but not as nice as the Corbin. (Corbin price is outrageous btw for front/rear w/backrests)
I have the carbon top/sides and the seat is fine.. If I wear my kevlar pant, it is slippery, with leather or denim, they are about the same as stock. Moving in the saddle for twisty roads is pretty effortless in leathers and like greased rails in my cold weather First Gear pant...
I have the backrest on the back seat and the Mrs does not complain at all..
If a guy is only going to be sporting around town or sub 300 mile rides, the Tobin is probably a super seat.. My ride days usually go over 500 miles however and the Corbin is in a league of its own for long haul..
I have not had to deal with customer service however, so I can not comment on how "user friendly" they are
