I have been vaping for awhile and about 7 months ago ventured into RTAs. I am a low wattage vaper, usually between 15 to 20 watts. I generally always use 28 gauge round wire with a 2.5 inside diameter. I have been told that an inline coil will produce less spit back but I find the flavour is lacking. I have gone back to spaced coils. Flavour is better but rewicking always seems to mess up the coil spacing. Any suggestions?
