I have been experimenting with RBA and been getting a lot of good flavors. On my rba, i been building 1.ohm micro coil and flavors on all my new fruit juices had been good. Before the RBA, I been using my protank with 1.1-1.4 ohm micro with cotton, with a menthol fruit juice and taste is good. And the new juice I got is all fruits and the flavors is not there with 1.1-1.4 ohm. Do you think 1.1-1.4 ohm micro coil is to low for protank? What is the lowest I should use for protank?
