I run my Derringers and Samurai Bonsai with a single coil and they work just fine that way. I used to put wick under the coil and let the other side go over to the other side of the deck, but I found it wasted more juice because that back end tail just kept it there and it never made it to the coil, and Im already sucking up enough of it as is. Now I just take one side and put some under the coil, the other side just goes down to the deck and gets clipped there. Just changed em all to this a few days ago after I saw a pic of one like it in the 'What are you sporting today' thread over in the mech forum and its been an improvement as far as efficient wicking goes.
