eh, whatever works. We don't lacquer ours (which makes us incorrect, as you are supposed to do that). Personally I prefer the mune-seam, it seems to form smaller welts.
My personal experience is that I simply get a large contusion and the exact placement of the "cutting edge" is unclear amidst all the purple, blue and green... I hadn't noticed that the placement of the seam made much of a difference on the headache that followed missing my move either...
