I just got my Brooks B67! Got here very quickly.
Oh, wow! This is the coolest thing! I am in awe!
First, it was very easy to put on my bike. It fit my micro-adjust seat post just fine, and adjusting the tilt and fore-aft was simple. The new leather is hard, like thick cardboard, and slippery. I'll proofhide it later today. The black seat, frame, and springs match my bike and it doesn't look at all funny or dorky.
Riding on it was amazing. I've never sat on a seat that instantly felt so great! And it's not even broken in yet. The leather doesn't feel hard when you're on it. Yes, it's slippery, but it's a minor issue that will fade and it didn't really effect the ride. My sit bones were happy, there was no discomfort in the "soft" tissues, and it was just so COMFORTABLE.
The nose is nice and narrow and doesn't interfere with pedalling at all. The change from sit area to nose is very abrupt, so I had none of the pinchy-rubbing of the insides of my thighs against a gradual change in width that I usually get when I pedal. I didn't notice the springs at all. No bounce. I think they did make the ride smoother, though.
The really wild thing is the difference I felt in my shoulders and neck! My arms and shoulders were so relaxed, and the little headache/neckache I usually get just never showed up.
I had no idea how uncomfortable my "comfortable" saddle was until I put the Brooks on my bike. It's like having a whole new bike, that fits me a bazillion times better and is a whole lot smoother.
