If DL is your style, the hadaly is not your best choice.
If you are using it on a mech, a 0.5 ohm or higher coil probably will not get the vape warm enough to be satisfying. If you are using a regulated mod, then coil resistance is less of an issue.
Also, in general, if you are running a single cell mod, single coil will work best. You can run dual coul on a single cell mod but it will eat your batterys capacity in no time and if you build a low ohm dual coil, a single cell mod will struggle to power it.
Appreciate the feedback on that...I'm gonna get the better ShenRay version and give it another shot....I've found a few single coil tanks I've liked so there has to be a single coil bf rda I like somewhere lol.
