I just got a B-17. Marinated it in proofide (slathered it on and put it in a black plastic bag on my car's front seat for a few days) and it is the MOST COMFY seat I've EVER ridden in just 166 miles of riding so far.
What a blessing to be able to ride without noticing my derrier!
I'm pretty certain that Brooks has ended my (seemingly endless) quest for a decent saddle.
