I have two brooks saddles. One is the B-17 and the other is the Flyer,pretty much a B-17 with springs. i have tried both saddles extensively on my LHT and can say that the Flyer is the one i prefer. Its a bit heavy though,not for weight weenys. The springs appear to be very stiff but they actually work and soak up what ever the frame and tires dont. The Flyer also seemed to break in easier,probably because it has a slightly softer ride so easier on the bum till one gets it broke in or it breaks us in. Dont use sprung saddle with suspension seat post or you will be bouncing all over the place. I find suspension seat posts end up getting wobbly after a time. But maybe i just rode with cheap ones.
