I just ordered both the B17 and the B68 a week ago from Wallingford. I was torn over the really sporty, smooth look in mandarin orange of the B17 vs. the rugged-textured honey of the B68 ( yes, somehow Bill still has the Honey color of the B68 even thought they aren't currently being made).

I started out with the B17 because I liked it better. I decided to disregard the sit bone measurements for now because Bill and Brent both said they really don't use those anymore. The B17 is the flagship model and has worked for so many people over so many years, and given my seat was level with the bars, I had a good chance of making this saddle work.

My sit bones were a bit sore, but I didn't feel like the saddle was too narrow or anything else. I did have to play lots with the angle and I'm not sure I ever did get it right. I got too excited to try the B68.

I have the B68 on the bike right now and really like that saddle. Comfortable out of the box. Feels roomy for the rear end. I biked to church with my family this morning and I don't even notice the saddle for once. Wile I love the aesthetics of the B17, this B68 is likely my winner.

Also noteworthy, I thought I would need an imperial, but so far, no issues. Everything just feels so well supported that even my soft tissue is happy.

I hope that my experience helps you choose! When in doubt, order both saddles!
