Well. I used a so called 2.5mm shoelace cotton from Firebolt and it's much thicker than 2.5mm as it was hard getting it through the coil but I persevered. Had to comb quite a bit out at the ends and tucked them indide the THC Elite MTL. Using the 1.0mm hole for airflow. Way too tight a draw even with the bottom airflow fully open. Tried vaping the Just Jam Sponge at various wattages (15w - 25w). Sweet but no other flavours and again too tight a draw. Will re-wick and use the biggest airflow plug I can tomorrow night and try again.
Wish I had pro friends that live close!
