Can anyone tell me for ego 650's should I use the Boge low resistance cartos or just the regular ones? I've been using the Smoketech dual coil lr's, which are nice and big, but they seem to drain the battery fairly quickly. I know I should bone up on ohm charts and all that stuff, but I had to place an order real quick, and since it's three hours past Rum thirty- that stuff is all Sanscrit right now.
