Donna, if I were you (which I'm not but hey....) I would get a B67 (like Knot's, and with the springs) from Wallbike.com (Wallingford's) and give it a whirl. You can also try their B68 (same wide saddle, but just without the springs, like mine).
You can RETURN either saddle to Wallbike after you try it for a while! How cool is that? Be sure to order a little tin of their "ProofHide" saddle conditioner when you order your saddle. If you put 'other stuff' on it they may not take it back, plus other stuff might darken the saddle considerably and/or make it too soft.
My DH and I both got new honey colored saddles. He put neatsfoot oil on his, I put Proofhide on mine. Mine looked the same honey color even after several Proofhide applications, his turned dark brown immediately and has stayed dark brown. Good thing he likes dark brown!
