I'm definitely the wrong guy for that. LOL! My coils are all in the .15ohm-.30ohm range. When it comes to higher ohm coils I really have no clue. Sorry.Hey, I use single coil RDAs on my mechs. Got any ideas for interesting coils in the 1 ohm range? I guess that's like asking Michelangelo for suggestions on painting my kitchen cabinets, but us MTL guys deserve some fun too.
