Clot Buster, Busted...

as you all know the default clot buster mut work up until about 4~5 waves then starts spawning scrakes ect, was wanting a mut that will launch just a certain type of zed, all the ones i found are broke as well. ( trying to make a all clot on HOE with mini guns and call it hug time :p ...)



or let me know which defualt zed only mut ACtully work, like 5 alarm siren and bloated... or do they all spawn other zeds after a few waves to?
