Whatever floats your boat, I think most people put the extenders next to the clasp though. I prefer mine in one piece without extensions, so I ordered it long. If need be I can cut off a couple wraps with nippers.
The one on the left was one of the first five DW sold. "halley" from years ago sent me some pics to see if I was interested... boy was I! The one on the right has a tiny bulge at the crown tube opening, it was the v2.0 case.
