I'm looking for something reasonably easy to build on that will support dual coils at low resistance and has a decent juice capacity (3ml+). Id like something with a wide bore drip tip and 24mm if at all possible so that it will fit properly on my nemesis mod. I had at one point been somewhat interested in the Cthulhu GAIA despite its 2ml juice capacity, though from what I understand it is an RDTA and requires tipping in order to wick properly. Any suggestions for a good 24mm RDA? Also could someone explain the rta vs. rdta thing? Do all rdta's require dipping?
