I wish I had some advice for you. I've only ridden my new B18 about 10 miles total, but it's not *the* saddle for me... yet (crossing fingers).
I've adjusted the height and the tilt (when it was level I felt like I was slipping forward too much and had to keep scooting back.
I didn't think about adjusting the tension- that's a good tip.

Have you played with forward/aft position yet?
