And when I use leaf hops now, they clog up my system without a way to keep them out. So I use either a hops spider as above, or a bazooka tube on my diptube. But that is after the wort is fully chilled, of course. so your "5 minute hops" are actually in there while the wort is cooling.
Some people actually do a "hop stand" or use "whirlpool hops", and add them at flame out and keep the wort hot for 20 minutes before chilling, or do a whirlpool with the hops in the hot wort. That maximizes the addition.
