OK, got my seat back today from Spencer. Took it out of the box and it looked just like the stock seat. Went out, popped it on and went for a ride. Upon first sitting on it, I didn't notice a huge difference, maybe a little spongier/bouncier than before. After about a half hour of riding, my butt felt the same as when I first got on. It's unbelieveable how comfy this seat is. I paid the extra 25 bucks for the supracor upgrade, and I'm glad I did. I could have ridden all day with this seat. This is possibly the best 75 bucks I've spent on my bike.
