Asking for advice on after market seats is sometimes like asking about oil: it depends.
I have used (and liked) seats from Sagent's, Corbin, and even EZ Berg. The one thing I have learned is that each offering for each bike is different. Each maker seems to have a different basic design (shape) for different model bikes, and each rider seems to have a different shape butt - so you would want to find a match to those shapes.
For example: the Corbin I used on my '85 K100RT was a vastly different shape than the one I first used on my 03 R1150RT. The Corbin saddle shape (that worked on my '75 R75/6) does not work well with me on the R1150RT, while the narrow Sargent's works great on it. Little things like the seat being too wide at the front can make your legs "too short" when stopping on unfriendly road surfaces.
Most seat makers will build with different "foam" density for different weight riders. They realize that 100 pounds body weight can make a difference in their designs at the end of a long riding day.
Most can match front and rear seats. As most now offer heated options.
I finally ended up going to a rally, sitting on all the seats in the vendor area, then ordering the shape and "foam" that fit my bike / butt / body weight / leg legnth.
The wrong seat can make a great bike a horror, and the right seat can make a nice bike great!
