Hi Deb,
You can't lose much by trying to sell it. The honey colored ones tend to sell extra well.
When I went from a B27s to a 'men's' B17 (non-"s") it was WAY more comfortable because I could slide it about a whole inch further back, thus improving my center of gravity on the bike.
Why don't you order the new non-s from Wallingford, try it out, and if you really like THEN you can sell the other one?
