I've got to where I like to find a vape on a RDA and stick with it. I've got a 454 running dual coils at .5 ohms 2 air holes shut off. I've got a magma wide open single parallel coil. I've got a doge wide open with dual coils checking in at .3 ohms. My next quest is parallel dual coils around .3 for a wide open RDA. (Hopefully something to either match or out produce the Doge vapor wise and increase flavor using the parallel coils.) I'm leaning towards the Mutation X V2 or CLT 2 Plus. I really want something with a t-block positive post because the extra space that it has to build parallel coils by off setting them. Any suggestions?
