Just got my first RDA. Picked up a patriot from a local shop. I only have the original Istick so I had to make huge coils to get to run in dual with a final res of 1.4. Nice flavor. Big coils mean a lot of cotton so unfortunately I get to taste that too. I expected that though, I have tried 3mm coils in my kayfun as well and got the same t-shirt taste.
