I think they look great with the lug sole. Chili works with everything, even a straight black sole.
Personally, I think bourbon looks best on the Strand, but given your situation, I can see how grabbing another Strand might be redundant. I'm going to take a stab in the dark, but I would guess that from your work description, your typical work shoes are "nicer" than at least 50% of the people around you. If your comfortable with wearing what you have now, then you probably won't have to worry about the level of formality. Don't know what your other AE's are, but the Carlyle an intriguing option; though I like the PA better. I don't thing the McAllister would look weird with chinos.
Somehow I don't think I've been much help.
LOL. I sort of figured that, but didn't want to sound insulting, so I gave my self some wiggle room. For the record, I was a Physics major, so I know the ecosystem.
