Hello and Welcome! I have been doing lots of homework and am learning the joys of manuals and rba's. I have 3 RBA'a now 1 Igo S, 1 Octopuss and, 1 Igo W. My first attempts at the Igo S had me making coils of about 2. Ohms but, on my Vamo these got minimal vape but, did produce some good flavors. My octopuss came with coils and wicks already wound at about 2. ohms. more later!
