1. I second the Delray suggestion, or even the Lasalle. I have the Delrays in chili and the Lasalle in brown, and wear both in the same capacity you mention (workhorse shoe for less formal work environment). Kenilworth is probably good if you like a plain toe shoe (not a huge fan personally).
2. Have you considered the McTavish or Elgin? Both are more "casual/rugged" versions of the Mcallister and Strand, respectively.
I really like the "natural wax" color of the McTavish, but really wish it was a blucher instead of a balmoral since I want to wear them with jeans.
Anyone know if there are any AE shoes in this color blucher style? The closest "rough looking" wingtip I could find in a blucher was the Rough MacNeil
