So I got the obs crius 25mm rta and for the life odd me I can't figure how to build this this. First build was 2.0 id with 24g kanthal @7 wraps for .25 ohm, wicked our with rayon and wicks barely in the channels and powered it at 50 watts and hardly no taste and vapor, bumped it to 55 and dry hits. So I rebuild and go to 2.5 id with same wire and came to .28ohms. Wicked with organic cotton and powered it up to 50 watts, this time I got juice spit back and barely any flavor or vape. But yet I do the same builds on a tfv4 with the dual rba head and get plumes of this tasty vapor. Please help me use this tank.
