I just upgraded to an itaste mvp 2 and got a rba to go with it. the guy at the store sold me 24 gauge kanthal wire and some cotton, I go home and try to build a coil(my first attempt to build a coil) and my itaste wont read the ohms or fire. what am I doing wrong? what gauge wire? how many wraps? on how big of a drill bit? im trying to get clouds and flavor. please help!!
