I plan on my next shoe purchase being an EG dark oak double monk strap. Is there any reason the RTW double monk offered by EG, as well as almost every other double monk I've ever seen, has a double sole? Is there any reason not to get a single sole? I've also never seen a double monk, or any monk for that matter, on a chisel-toed last. Would a double monk be better suited to the 888 or 82? Also, cap toe or plain toe?
