I haven't riden a Flyer, but have a B-67 (sprung), B-68 (same wide saddle unsprung), B-17, C-17, and C-17 carved, so I may be able to offer something... The coil springs on the Flyer/B-67 are at the rear, so they compress only when you are sitting back on the saddle, and they are pretty stiff. I've heard some say that they don't respond at all if you weigh less than 180 lbs/82kg, but I think that must come from those who ride with little of their weight on their sit bones. In a more typical "road" position, the Cambium, and especially the Cambium carved, will be as flexible or more so than the Flyer ridden the same way. So you really have to analyze the way you ride to choose the best saddle for you, and try them out if you can. That said, wider tires with lower pressure will do more to absorb road shock than any saddle. I used to have my B-67 on a Bianchi Milano with 26x1.5 tires. Now the B-67 hangs on the wall and my Bianchi rides much better with a B-68 and 26x1.9 tires at 45psi. On my Sam, I ride a C-17 carved and 650bx38mm tires at 55psi. If Brooks would come out with a wider Cambium, I'd replace the B-68 on my Bianchi—I like the Cambium that much!
