I just got my flyer today and went and rode about 20 miles on it. I weigh about 330 though, and I could hardly feel the springs (at least to the degree I expected. I imagined it feeling like it would on one of those old cruisers my parents rode). I suspect they will loosen up over time which may make them a little more useful. One of the people I was riding with said she could see them flexing a bit when I hit a bump, although I've never used a brooks before, so I didn't really know what to expect, nor do I know what a non-spring brooks feels like. It was super comfortable though, even straight out of the box. I'm not sore at all, and the last time I rode 10 miles on the stock seat on the LHT I was ready to quit. I can't wait to see what it feels like in another 1000 miles. I need to get to work on putting those miles on then.
