Has anyone used the IGO W-4 on the iTaste MVP version 1 yet? I know I can't go below say 1.3 ohms or so and I also have to raise the connection switch up some so the IGO makes connection. What gauge Kanthal do you normally use for this set up and what size silica? I may try cotton and build a micro coil, what size drill bit is best recommended to wrap the Kanthal around? Thanks everyone!
