I am a flavor chaser. I have found that different brands of wire give you a slight difference in resistance. Currently I have found a twisted double 28G or triple 30G Alienwire to give me best flavor. Using 454 Big Block RDA, vertical coil, 7 wraps, 2mm diameter, 0.8ohm on a mech mod with LG 18650 HE4, Cuttwood Boss Reserve/Unicorn Milk e-juice.
Try to find a balance in the number of wraps to get enough surface on the wire with your target resistance. I find 0.8ohms to be almost perfect for a mech mod. Also adding or reducing a wrap and smaller or larger inner coil diameter makes a large difference in flavor.
I suggest trying to get the resistance you like then work at either a smaller or larger gauge wire and wrapping it to get the right amount of surface on the coil. I find myself only working with 2mm and 2.4mm inner diameters. I prefer the 2mm inner diameter, but if you are using a small chamber RDA such as a derringer sometimes you can work with 2.4mm (depending on juice) to get a smoother vape. I find a larger diameter tones down the flavor.
Your wicking also plays an important role. It has to be just right. Too tight it will choke, too loose it will not produce sufficient vapor. Make sure its snug, there should be a little resistance when you tug at it.
Dont be afraid to waste wires during your first few weeks. Have fun and happy vaping!
