Before I started vaping (in 5th month now), I did a lot of homework on the tech details of how the whole thing works. Based on my studies, I elected to start out with high voltage and high resistance (we'll call it LC for low current) setup. On paper, this appears superior to HC (high current) setup in every way, and for the most part I've been satisfied with it. However, I keep hearing how many vapers prefer HC due to an extreme difference in the taste and texture of the vapor, and willing to pursue this at the expense of battery life and convenience in general.
So I am left wondering about the science of it. What exactly is happening at the point of vaporization that makes HC produce a different type of vapor than LC at the same output power? The answer to this is my goal for this post.
I haven't much experience with HC vaping, only having sampled from other peoples' ego-type units, but in that I have noted that the vapor is "fluffier" and the taste of the juice is closer to what it should be than it is on my LC rig. The most notable difference between the two is in the coil - assuming the same or similar gauge resistance wire, the higher resistance coil is longer overall (6 turns versus 4), thus there is more surface area to the heating element creating more vapor.
My initial hypothesis is that the larger coil is putting out more vapor within the same volume of space, and thus comes out denser due to the fact that the vapor can be compressed back into a liquid by pressure alone without cooling. I suspect it is this increased density that causes differences in flavor, as I have noticed that a juice which is balanced in your standard ego/clone becomes embittered in the LC rig, closer to the awful taste of raw juice in your mouth. If this is the case, then one would think the juice could be balanced for LC vaping by simply diluting it with more PG/VG.
Anyone have any good technical insight on this?

) point - if you're delivering the same wattage through a smaller volume, you've got a hotter vape. Maybe it's simply that, and that should be relatively easy to test.
