I dunno that I'd ever actually use em, but they are in all seriousness too cool looking to pass up (and generally speaking I never give a darn about such things, but these for some reason just look great, even as a sort of art display on a shelf in the lounge room :) ), esp if there only ends up being a few sets ever produced. I'd be up for a set of whichever you get 4 other orders for (probably a slight bias toward the longer version, but I'll go with the flow if that makes for enough confirmed orders to make it happen)
