I ride a flyer on my mixte road bike that I commute on, and I recommend it... my handlebars are about even with the saddle, and basically, the B17 and Flyer are identical except for the springs, so on my pothole and tree root on the MUP ridden commute, I like the springs. Though as I don't weigh a whole lot (less than 150 lbs). I actually find it possible to be bounced up out of my saddle when I hit some big bumps-- but if you are a larger male, perhaps this should not matter. Otherwise the springs are very stiff and don't flex at all.
