Sure, of course, it halves the ohms. More amp draw.
Never tried a dual coil carto so I can't say if it makes a difference or not. Sure makes a huge difference in flavor, throat hit and general intensity on a genesis.
It's not for everyone I admit, but it certainly does provide a much different experience.
It's not just about halving the ohms either. A single wick 1 ohm vapes differently then a dual wick 1 ohm. Twice the wraps in the dual coil setup. The vapor is pretty intense. Like it or hate it, it's a good option to have since you sacrifice nothing by having it...other then a couple extra screw heads under a top cap you don't see very often.
