I agree with Skelee. I have the Yamaha "flat" seat this year, and I like it better, in most reguards.
I think I will send my stock seat to a shop, (possibly Brogue) and have it reshaped/recovered.
The rear shock is one of the only other weak points.
Consider looking up a local car/bike seat upholsterer to see about reupholstery, you can work with them, possibly do a ride test with the foam before upholstery is done to see about reshaping. Off the shelf stuff just doesn't provide what custom work does and with some research you may find a local upholsterer might be lower cost too.
You can also talk with local Gold Wing and other touring riders to ask about their seats. They will know who can do what. Fact is there used to be a company that did seats custom fitted. The seats might look a bit weird, but they were fitted for comfort.
More often than not, it is a craps shoot if you buy a seat, especially if you are going by looks. Looks don't make comfort. Plus it is all about personal fit.
Best seat I had for fit was the stock 1984-86 Honda Nighthawk S, thick and flat. Oddly enough, the thin 1983-85 Nighthawk 650 seat was really good too. I have had seats done locally and only had one fail - too soft on the foam, bottomed out when I sat on it.
I have the solo and I put gel pad in but now i am thinking doing stock one.
I found the solo saddle to be really comfortable. Big enough to move around a bit. It really worked well for me. For the price it is a good buy.
