Can't speak to your problem, but I've not found the B17 to be the magic saddle that many folks praise. The slick-ness will not be a problem after a while. My comfort level increased initially, but after 500 miles or so it seemed to level off with no change in the last 1,000 miles. I'm used to a narrower and longer saddle (SI Flite). I prefer the Brooks for rides over 50 miles but it's not as comfortable as I thought it would be. I may be trying one of the Specialized saddles when the fall sale prices begin.

edit - forgot to add that on fast rides where a bit more aero position is desirable the Brooks is even less comfortable for me.
