I have one, but can't tell much difference between the flyer and my B17 as far as how much more springy or cushioned it is vs the non-sprung saddle. I don't ride it too much, so maybe it's not as broken in as my other brooks seats. One thing to look out for is the bolts that hold the rail to the spring can come loose. I had one fall out and had to replace it with something similar from home depot.
