The filament monster is probably because the nozzle has a less than perfect seal to the hot end, causing the molten filament to leak.

I don't know if your hotend is an all metal one with a heat break or one where the Teflon tube butts up to the nozzle. If it's a teflon tube one, a long print time can cause heat creep and lead to leaks and clogs, especially if the end of the tube is not perfectly square and a snug fit. Also repeated heating can deteriorate the tube.

An all metal hotend with a heat break is a better choice, just heat up the hot end to about 20 degrees more than your normal print temp when you put a new nozzle in and then nip it up, this will seat it hard against the heat break.
