Tried my first 3ohm coil. Quite a difference. At 4.8v., it always felt I was on the verge of burning with the 2ohm, so would only take a couple quick draws, but with the 3ohm, that concern is gone. The flavor is definitely brought out more at 4.8v. Have only tried with 1 flavor, though, as I only have 1 colored tank, until my order comes in this week. I may have to convert over to all VV batteries. Too bad they don't make a 400mAh version. That would probably fit in my VEA case; as it is, I'll keep using a pair of 650's for when I'm out and about.
