your Ego twist has I believe a 2.5Amp limit, so you wont get the max vape on a Genesis set up with a Twist, even if you crank it up it will only put out a 2.5Amp max I believe, You Need either a mechanical mod with an 18650 IMR, a VV or VW mod with a 3.5-4 Amp limit to get a decent vape. Also .6ohms is to low,, get er up to 1.3-1.5ohms, just my opinion, your lucky you didn't fry your twist at .6ohms as well, I wouldn't keep using that set up.
