I think the standard way they are made would suit me fine for a mech in single coil mode, I don't mind a slightly higher power vape every now and then especially as I am now making my own juice again, don't have to worry about drinking too much juice now.
I dont limit my self to a wattage range, got a few 22mm single coil RDA's with a 2.5mm coil running at 50w+ vape awesome, helps being on 21700 squonkers.
