I have 26 gauge SS and will use 2.5 or 3 mm from coil master to wrap my coils. I usually build the kayfun V5 with 2.5 and my Squapes with a 3. I just wasn't sure what resistance I should be aiming for. I also won't go crazy torching it to clean it. I pulse with kanthal and never glow them. just heat it up enough to clean it and dunk the base in water to cool it and get the gunk off.
