If you got the B17 from Wallingford, you have 6 months to try it with no questions asked. The B68 is only a little bit more expensive, certainly the difference is cheaper than a Terry!

Terrys are not wide enough for me.

And the pear shape (gradual transition from nose to perch) of most saddles is terribly painful for me. I have a Serfas Niva that is nearly wide enough, but it's that gradual pear shape that chafes me and makes the saddle a bad fit for me.

Here is my Serfas Niva next to my Brooks B67:


The Serfas has some goofy painted stripes on the trasition area, but you can see that even this saddle (the most T-shaped I could find at the LBS) has a more gradual transition than my B67.
