I'm not a huge fan of the chunkier Grenson Brogue either, I would go for something slimmer like the Dylan.
This is another Barker brogue, it might be a touch too formal, but I think it's fine.
I'm eyeing up these for the winter, my Hudson Brogue Boots are too big (I seem to have lost weight on my feet)
