I know the feeling! I'm having pretty good luck w/ the EM's that Rob has on sale on his site. When they start to clog, I drill out one of the holes w/ a 1/32 drill bit. One problem w/ them though- I haven't figured out how to de-bridge them yet without affecting the ohms... There is a circular sleeve in them and if you're not careful, you'll pull the entire coil up when you try to mess w/ it. I've learned to leave this atty alone- they are cheap enough...when they go, they just go... p..l..i..n...k.......
