This was the only point that I had. I don't know where i got the info (doubt it was in a text book, though) but if you have very different diameters you can have troubles with the EDK slipping a bit. If I do use an EDK with two greatly different diameters I pull each and every tail (all four) in the knot individually, sometimes twice, to make sure that the knot is really nice and snug. Having said that the biggest difference I've ever used would be around the 8.5mm and 10.2mm diameters... (thinking about what ropes i've had)
