@TimWV WOW, that’s a loaded question. Hehe, well, kinda.
I can’t speak firsthand to the glorious benefits of the exotic coils, BUT, we can still talk. Larger, more complex coils typically have much more SURFACE AREA. Now to many people that automatically means MO MO MO right ?? MO this, MO that. Well, MAYBE. If surface area WAS the only game in town, THEN, you, I, and many, many other people would NOT have great results with single wire coils, right ?? I think more surface area CAN help, but it’s NOT the silver bullet. It can get to the point, where there is literally SOO much wire mass, that trying to heat the damn things up, and KEEP them heated, is a real PITA. You can run parallels to try and drop the resistance, but every time you do, you add MO mass.
The one thing that I think often times gets overlooked is the AIR. Where is the air hitting the coils ?? Lower sides and bottom ALWAYS give me the BEST, saturate flavor. Tanks are my style, so I can’t speak to RDA’s indepth, except for maybe the Elder Dragon, hehe, and THAT little sucker is a FLAVA MONSTA. Single coil at that, and it is a flavor chucking monster. Some tanks just plain SUCK. No coil, or airflow can fix them. More often then not, tanks that pull from top airflow (nder the guise of no leaks) always seem to sacrifice some flavor. There are a few exceptions, but typically my best performers are bottom air flow, and YES, some of them can leak, some will ALWAYS leak if you put them on their sides, BUT, flava rules the day for me.
Different coils are going to require different amounts of power, ramp time, etc., so there’s no one setting for all of them. The fact that you tasted a big difference in the frailiens vs. your cheaper claps, or single wires, is VERY telling. I would be curious what wattages you were using for them, and how/where the air was hitting all of them.
