You don't yet have a derby, so the Kenilworth would certainly fill a hole. On that front, you could check out the Leeds too. I'm with those on this thread that wouldn't pair Daltons with a suit (I have Fifth Streets for that). I really like the Fifth Avenues but I think they would overlap a little with your Strands.
Are you not into merlot/burgundy? The Leeds in burgundy shell is a pretty penny but an absolutely gorgeous shoe.
Agree with this. They are my oldest shell shoes and still one of my favorites.
