Yeah, the single sole on the Finch was actually my only negative on it. I think the split-reverse welt adds some substance to it's profile, so it still looks perfectly balanced in my opinion. I just like the idea of a double sole for durability sake. The Elgin and McTavish are definitely both made of cowhide. As I said in my previous post, I think the sole on the Shelton looks rather refined in spite of being a double sole due to it's rounded profile and traditional welt. I think the split-reverse welt on the Finch with it's natural color contrast against the tan upper actually creates a similar level of heft and therefore they are about the same in my opinion regarding "clunkiness." Yes, I think it is the heavy leather combined with traditional men's dress shoe styling that puts all of them into the same niche (color differences aside). I absolutely love every Rough Collection shoe that was introduced last year (not as much of a fan of some of this year's introductions), and I think there is enough differences between them to warrant having all of them if your budget allows.
