LV DART is about 1.5 Ohms, I don't have a AVA but suspect it's the same?

I'm not sure about it. I saw the coils in the AVA and DART and there's a difference in the amount of wraps that I can see. Plus, it takes longer for the DART to warm up. I tried it with some juice after cleaning it (my AVA threads are stripped to hell but everything else I've put on my Ultra works perfectly) as a temporary replacement/see if it was worth it, and it took a noticeable amount of time longer to heat up/get that light gurgle.
Anyways I did end up swapping out the 2.4 for the 1.8 and I think I like this one more.
Thanks again for the knowledge. I'm getting more and more into the more technical aspect of ecigs (rebuildable atomizers, wick types, wire gauges and wraps relating to ohms, etc) so I'm sure the info will come handy later on down the road.
