Single coil vs Dual coil is personal taste... saying one is better than the other is like saying coke or pepsi is better.

In a nutshell, you can use dual coils just fine, but you won't be able to crank them to higher voltages. There are 2 coils, so at any given voltage it's drawing 2x the current giving you 2x the watts (2 coils, makes sense, yes?). A 1.5 ohm dual coil cartomizer would draw 16.666667 watts at 5 volts, so it would be a no-go. You can find higher ohm dual coil cartomizers... a 2 ohm dual coil would draw 15.125 watts at 5.5 volts, so you have options. For reference, you can go to Ohm's Law Calculator and input whatever voltage/ohm combo you are curious about and it will give you a wattage calculation.

Dual coil cartomizers really do shine at higher voltages. Some people prefer single coil cartomizers. Try both!

Is the 2.5 ohm dual coil two 5 ohms in parallel, resulting resistance 2.5 ohms, or is it the second case, two 2.5 ohm coils in parallel, 1.25 ohm total resistance? I've been seeing some smoketech 1.25 ohm DCs around (two 2.5 ohm in parallel).

If it's a smoketech 1.25, then 15 = VxV/1.25, V = 3.46V is the highest voltage you can reach and stay within notcigs spec. They might work, just barely, by setting the voltage at the lowest end of the scale.

If it's the first case, two 5 ohm in parallel, sure, you could use it, all the way to max voltage, since that would still only be a bit over 12W, each coil running just over 6W.

Think I'll stick with my single coils, 2.5 and 3.1 ohms :) Reasonably low cost, wide availability, work nicely.

Several people around here like 1.5 ohm DC, which can be used at up to about 4.7V.

(It isn't that DC won't work, just that most people use DC on lower voltage devices, essentially trying to replicate what you can do already with a buzz product on single coils. Higher resistance on a buzz PV leads to longer run times between charges.)
