Awhile back, while searching for MTL RTAs, I made this "wishlist" : GEEK VAPE AMMIT 24MM MTL RTA Coppervape Hussar Project X Styled RTA INNOKIN ARES 24MM MTL RTA Fumytech Rose MTL RTA CTHULHU MOD HASTUR MTL RTA MINI EHPRO True MTL RTA Berserker V1.5 Styled MTL RTA COILART SALT 18MM RTA ULTON Tripod Style 316SS 22mm RTA SILVERPLAY 24MM MULTI AIRFLOW RTA SXK Doggystyle Styled RTA I would like to add Max airflow (wide open) ratings to the list. To keep it simple to understand, I want to use the equivalent airflow of a single hole. If you don't know, I will do the math and convert... just say "two 1 mm holes" or even just compare to another RTA and I work it out. Doesn't have to accurate... just a simple way to compare them. Feel free to add to the list (please keep it MTL but include "loose" MTL) Thanks.
