I don't use that tip anymore, actually. It's too much of a pain. Just use a toothpick to dig a little out of the normal tip.
Also, I've found a little 'sample' sized pack at Hobby Lobby. There are 4 tubes (2 E600 and 2 of some other craft glue) and the tiny tubes have tiny nozzles. It costs more, but I kinda like the size.
