I seriously considering getting the seat as a present to me. I've read it is a no-mod bolt on. Looking at the seat at their site I don't see how the back of the seat attaches. Can anyone talk to how the seat mounts?

Bolts line up the same, but It will be more difficult to acces them, becuase the seat is stiffer underneath. I switched over to allen head bolts. This made it much easier to take off/on.

Definitely just you.
I loooooooooove my Corbin.

I absolutely love my Corbin seat but when I first sat on it I was definitely surprised.  It's much more of a bucket seat and you sit more forward on the bike.  For me, I had purchased Routy's Forward Control extension brackets and was debating putting them on before I got my Corbin.  I'm 5'9" and wondered if 6" extensions would be too much of a reach.  After riding around on my Corbin for a few minutes it became clear that I needed to put those extensions on.

But with the combination of the forward leg position on the Corbin seat, I'm in heaven.  A few days after getting the forward controls on I set off on a few thousand mile road trip and I couldn't imagine doing it on the stock seat.  One thing I know from my bicycle touring is that soft seats feel nice in the store when you try them out initially but for long distance a firm seat that fits your sit bones will get you farther than the road every time.  I never once had any of the soreness on my trip that people said I'd get used to.
