I just like 20awg wire. In my opinion (as is with everything - subjective), I find the flavor and warmth of the 20awg wire to be perfect. I thought 24 was good, then I tried 22 and 20, and the lower I got the more pronounced my flavors became. I also like the heat retention on the lower gauge wire as well. It keeps the chamber on my dripper nice and warm without affecting the overall use, function, or anything else for that matter. What also helps me with liking the heat retention on the thicker wire is - granted, sometimes takes a bit to warm up on a completely cold coil, but after its warmed up, since it retains heat longer, as soon as I go for that second pull, it takes less time to heat up a second time. Again, I enjoy the warmer vapes, the more pronounced flavors, and quite honestly... the overall ease of use. 22 and 20awg - if you've ever worked with it for prolonged periods of time, you notice again - opinion - that it's a lot easier to mold coils with than a lot of your thinner wires. Torching is totally optional on all wire but I find if a minor error on a thinner wire happens, it's much more difficult to fix without torching, quenching, and pinching or completely rebuilding than with your thicker wire. 16awg - well - that's a completely different story. I've built a few coils but got nothing to install them on, and although torching becomes almost a necessity with 16 than the previous 2 gauges I've spoken about in this post, I'm almost guessing that after I work with it enough, I will figure out its pros and cons.
