Corbins are hard as rocks...Lepera's are a little softer. It's like he said, It's all in the style. A little sport seat is going to be hard no matter what. Some of it has to do with You!......A guy 180 lbs with a skinny ass is sure gonna need a different seat than somebody 270 and a large.......well you get the idea!
I have a Lepera, it is a high quality seat and yes it is kinda stiff(a sport seat)... but nothing like the Corbins I've seen!
I bought a Maverick for my 2002 FXST and had to return it because it shifted me forward 2 1/2" to 3". It was comfortable enough, but I couldn't ride the bike to to the fact that I was sitting way too far forward. I am only 6' 2" and the seat would probably be fine if I were shorter. I didn't plan on a foot control extension kit, but may have to go that route. I will see what other seats might fit.
