Bloody good idea, mate.
Actually, I remember you telling me this once: in one ear and out the other.... Could have been something to do with the logistics of stepping up from the 1/4-inch nozzle to .40, .45, .47 and .577! Also hard to find a pencil-sharpener for 0.4 to 0.6 dia pencils!!!

OK, Ok, I will give it a go!
