Back to the op, I am hooked-with different juices, mind - on the ego with a Resurrector (1.7ohm smoketech) and the 5v RSM with a 1.5 DCC. I know others nay say the 1.5 DCC at 5v and maybe it's just the way Cappy builds them, but OMG tobacco and bakery comes alive there! Just my experience, at 5v this has been for more than 5 months, so I am not just trying it, I really use it every day without fail.
Everyone likes different things and has different equipment. Good luck to you finding what works perfectly!
