I was unaware of this, thanks for sharing. In fact, AE web site says to use walnut polish on bourbon shoes.
This is what I was implying a previous post when i said I preferred the PA over the Carlyle. On its own the Bourbon Carlyle is HOT, but given your typical work attire, seems a little plain, IMO, between the 5th Ave, PA and Carlyle, I like the 5th Ave best with chinos. My order of preference (MINUS Strands) is 5th, McAllister, PA, Carlyle. You asked it the McAllisters would look weird with chinos, my response: not at all. But since you see to be a little Brogue heavy (with 4 pairs of Strands), the 5th Ave sort of bridges the gap with just a touch of broguing.
In so many words, my wife said the same thing. And I happen to agree. if i didn't have 4 pair of Strands, I would go that route. But like you and my wife say, the 5th Ave bridges the gap.
