Which Cubis Coil for my AIO?

[Em-33]

First I apologize for not doing more research on the Forum or Google but I'm out of time.
I've gone through 3 new coils in 4 days so I either have a bad batch or maybe the wrong kind for my AIO?

Are joyetech Cubis coils the only ones I should be using? And which ones produce twarmer vapor?

SS316-0.6ohm Head is what the joytech AIO is suggesting on the website Em-33. I use the cubis tanks and the closest resistance I use is the 0.5 ohm DL, 15-30 W, it is a SS316.
The SS316-0.6 head is a 15-28 W. So that's probably the closest to what came with your AIO. You can find it here Joyetech Cubis BF Replacement Coil (5 Pack) - SS316 - 0.5ohm looks like it's out of stock rite at the moment
