I've always thought the Corbin solos were the best looking seats, so when a set went up for sale on the parts and bikes Facebook page, I grabbed them. I wanted to see how it fit me compared to my E.D. Seat.
First, the solo Corbin weighs 8 lbs. The E.D. 4 LBS. The Corbin is much firmer. I think it's leather, so maybe that has something to do with it. Both seats sit me the same height and distance to bars. However, with the Corbin, my stance is wider. Each foot is out 1 inch further, due to the width of the Corbin. May not sound like much but with a 28 inch inseam, I find the E.D. feels better in that regard. The lack of a backrest isn't an issue as an after market one can be had for the Corbin.
As far as looks go, there's no comparison. The Corbin with the pillion looks a hell of a lot better than the E.D. with that giant but probably more comfortable pillion.
So I think I'm sticking with the E.D. because it just seems to fit me better. If I was younger I'd probably go with the Corbin, as form wins over function when you're younger.

I think your ED seat looks better, but comfort should win over. And that's a great looking bike, regardless of what seat is on it.

I've had both Corbin and ED. You made the right choice. The Corbin was FIRM and I never got it to fit me. The ED was good from the first ride. You will be happy with ED.

The Corbin's been on my mind the last few months. I'm glad I had the chance to try it. Now just have to wait for the weather to change here in the NorthEast. Hope the guys in the great climates appreciate where they're at.
Update. Sold the Corbin this morning on parts site. Can't wait till good weather, so I can spend money on gas, not parts.
