I just built my first genisis-style rba (smoktech rsst). I used 29g kanthal (28 was out of stock) and did a 3/2 wrap on mesh. According to my multimeter it's coming in at 1 ohm. Does that sound about right? I've checked for continuity and used it for about an hour, and seems to vape well--especially with a fresh battery (on sigelei 20).
