Tried out both stretcher bond and quarter bond for concrete blocks (sides in stretcher, rear in quarter).
Both work, but quarter bond is a lot more fiddly to keep level and so not as quick to lay.
So (especially as I have now hired a noisy dusty cutter) I have gone over to stretcher bond for the rear as well after the first four courses. Nobody will notice unless they feel the need to crawl along the bottom part of the gap between the wall and the fence.
