I had a flyer on my brevet bike and the bike I did the ironman with. I found that on a long ride, the spring helped to take the edge off and kept me comfortable longer. I never had any issue with bounce, but it did take a few hundred miles before it was really comfortable for me. My average cadence is 95-100 but I often spin up to 120-130 during rides and I never bounced due to the springs. When I got a new road-bike, I went with a B-17 narrow, mostly due to cosemetics...I thought the look of a sprung saddle on a CF bike would probably kill any cool factor I might muster from the looks of my bike. I find that with the B-17 I raise off the saddle much more than I did on the flyer, and that my endurance is still adequate for riding distance. I moved my flyer over to my breezer-8 commute bike, and it works great there. The combo of fat tires and a sprung saddle makes it like riding in an old caddy...weight included Hope that helps.
