Going from using rda's at about 45 watts with .4 ohm kanthal to the world of TC. I plan on a IPV4s with a uwell crown (with rba deck). I plan on trying both Ni200 and TI wire. Eciggity is the only vendor that I've found that has all this in stock (except Ti wire). I've tried to do my homework but thought I'd asked for input here before "pulling the trigger". Any input or suggestions would be most appreciated.Thanks Jim
