My seat just arrived a few days short of the promised 4 weeks.
It is a firm, but comfortable seat. It feels more like sitting in a captains chair versus straddling a post. There's more support for the upper thigh, which points my legs straight forwards and snug against the tank, whereas on the original seat they rest naturally in a more akimbo position.
I've only ridden it a couple miles, and I won't have a better assessment until the weekend, but so far it is more comfortable to me (maybe it is just the thinner wallet).
There is an argument to be made that Corbin should use gel, and some people just aren't comfortable on their seats, but I can't find fault with the quality. It is a well made seat. My last aftermarket seat started coming apart at the seams in under two years, and I won't make that mistake again.
All in all, I'm pretty pleased. It is a bit more yellow than I had in mind, but I imagine it will age to a more neutral tone. More importantly, my ass doesn't have eyeballs and doesn't care.
