I'm clueless on what guage wire I need and the ohm and all that. Everyone is saying that 2.5 mm is the perfect size cause of wicking issues. What do they mean by 2.5? Also I see all different options like hive Clapton coil Clapton alien tiger please can someone tell me the exact wire I need that is 2.5 mm and stainless the rest I don't know what I need for single coil. Also I just want to buy premade and supposedly there is a new avocado 24 out that has bottom airflow that makes wicking and flavor better. Any info will help I know I have to buy a ohm reader and all that
