You are quite welcome. The EG oxford you have shown (appears to be the Chelsea) happens to be a pair I own. Of course those will work. As for a JL captoe model along those lines, you can't go wrong with either the City II or Phillip II:http://www.johnlobb.com/us/models/oxford
I don't think the Chapel would look aggressive or odd; however, of the four you list, the Chapel would be the least formal IMO. The other three are reasonably close in formality, all very appropriate with a DB suit.
