28g, on a 1/16 drill bit, 8 wrap dual coil. I am using it with cotton wick on the Stillare V2, getting VERY good results. Close off about 3/4 of the air slot, gives very flavorful and warm(not hot) vape, very satisfying setup. Using the Cartel Stillare V2 clone on a Nemesis clone, Sony VTC 4 batteries.
