Yeah, I decided to order the copper model when I get the chance next week, just to be on the safe side to make sure I get the best performance. Was curious if anyone had recommendations on good RDA's that are copper? Right now I'm using a copper mini Buddha (the 24mm version) and I couldn't be happier with it...for the longest time I thought, and was told, that the Twisted Messes and Twisted Messes Squared were the best RDA's, but the airflow I get with my mini Buddha puts the TM RDA's I've had to shame and was curious what other RDA's I might have dismissed and been wrong about. I use a .12 dual coil triple-strand parallel build which can get pretty hot, so, need the great airflow like my Buddha. I've heard mixed reviews about the X1...some say due to the low airflow holes it leaks horribly, but others say that concern has been addressed and fixed now, but if there are other copper RDA's I may not have heard of I'd love to hear about them Sent from my iPhone using Tapatalk
