i just made a twisted 26GA 6 wrap coil tight..don't know if you would call it a microcoil. turned out at 2.4 OHM in the Tugboat. i swear that is what this thing is made for. short drags. 60/40 vg/pg and the taste is phenomenal. monitoring how many toots i get before i have to change batteries on a 2 second drag....i like it...boy howdy! this thing rocks the Shotgun mod....peace <*}}}>{
