I, too, switched to the non-granny after reading Ian's site but then switched again to the fake magician's knot where you make a loop, pull another loop partially through, then tighten - the ones where pulling the loose end will undo it "magically". Works great, basically never comes undone, takes seconds, and is a lot less fiddly for old people (like me.) (Think it's called "The Dissolving Knot Trick" in magic circles.)
