When I was on the phone placing my order with Corbin, I was asked my inseam and weight. I was told that the seat would form to be mine with the correct 'feel' once broken in.
I have been treating the leather weekly, as per Corbin's advice to aid in speeding up the break-in process. I currently have ~1700 km (1100 miles) on the seat, and I'm really liking it. It hasn't given me any fitment problems. It is firm, but very supportive for me. I didn't get the backrest, and I have no need for one. I had Corbin delete the backrest opening on my seat, and I have no regrets there.
My wife's Speedmaster has the stock seat, and in comparison I feel lower on her seat, and support is dearly lacking, especially for my back.
One size doesn't fit all, so I can certainly see how others may not agree.
These seats are expensive, and without the ability to try one on in the store, there is some risk there for sure. I bought the Corbin due to the recommendations from this forum.
