Wow! Thanks for the answer, really thorough thanks for taking the time, I feel like I am more equipped for this now 
Hey @ConradS
Well for starters you can expect a more 'intense' vape.
- Dual coils (at least in my opinion) pack a mean punch. They hit harder from my experience.
- I find that the dual coil setup is also great in terms of flavour. Call me crazy but I have tried several liquids I know well in a single and dual setup and the flavour in the dual setup to be enhanced.
- I have also found that some liquids that tasted average on a single coil build, turned out to be incredible on a dual setup.
- You will also get the chance to enjoy even greater airflow now as you will be opening up another airhole slot for air to hit your second coil.
- As a result of this increase in airflow and because you have a larger surface area now in a dual coil build ( I.e double the amount of wire, vapour production will also jump.
Note:
- A con to the dual coil that I have found is that it guzzles a lot more juice.
- Make sure both coils are as similar as possible to one another.
- Dual coils really come to life around 0.6 or lower (in my opinion)
Going from a 1 ohm setup directly to sub ohm dual coils might be quite a jump for you. (Very different experience)
My advice would be to perhaps experiment with some lower resistance single coil builds first to dip your feet into the sub ohm.
Or you could just go balls to the walls
Please do not take any of the above as gospel. It is merely my opinion and experience over the last few months.
Hope this has been helpful
Here is a dual coil I did In my atomic a while back.
