The 2.0 will give you a good all around vape. That's what I use on my Kgo,I've tried the 1.7 and on somethings it was good and others it seemed to hot (almost burnt). The 2 is good middle of the road, 3.0 seemed a little to cool and not much vape.Mostly I use Boge 2.0 single coil and get good vapor,throat hit and long battery life.
Okay. Good. Thank you. I was hoping I didn't mess up ordering this extra stuff and I've read great reviews a nd videos on he kgo.
