I've got a sigelei 75w tc with a herkales tank. I typically vape at about 52 watts on power mode and get pretty good flavor and vapor. I CAN NOT get the same flavor with a nickel coil. I use Atlantis coils .6 ohm power and the .2 nickel. I've tried everything for tc and the only thing that seems to work is running the wattage about maxed out because I like a warmer vape. Is this normal? The guy at the vape shop said he runs 35w at 480 degrees and to me it's awful. Any suggestions would be helpful. Thanks!!
