I own a B-17 and for me, the tilt adjustment made a huge difference. I have one on one bike but I haven't gotten one for my Aurora because I'd need to get a better seatpost (for my tastes) to be able to tweak the heck outta the tilt. It's taken me awhile to get the height, tilt and such...just right on my other bike. But the rest is just a matter of breaking in. I'm in no pain when riding. You shouldn't be either. Brooks saddles take about - (dare I say this?), 1000 miles to fully break in - according to the guys/gals from Brooks. I feel comfortable already, but it's just a more finicky saddle.
