I found what worked for me in the True was 2.5 Mtl clapton around .9ohms. Coil like Matty about 1mm above the air hole. Wick to a smidge above the bottom of the cutouts and thin the ends. Most of the tutorials don’t thin at all but for me personally the closer I got to omg this is about to flood the better. I’d often find myself wicking and filling and then going back to just nip off a teeny bit more. I don’t know why but it just worked for me. Unless I was lucky I’d always have to work on it to get it right.
