You should absolutely switch from cartomizers. The attys of today are so much better and have been for years. Are you at least using a carto-tank? Anyway I don’t really have an answer for you as I use 50/50 juice but someone will be able to help. I just needed to say give up the cartomizers, today’s gear is light years better. Man you are in for a treat but you may need to lower your nicotine mg’s of your juice because you get instant flavor clouds with today’s stuff. I take 2 second puffs at most and it’s totally satisfying. I quit smoking using cartos but wasn’t truly satisfied until I started using 0.5 ohm attys in a proper tank. They vape great at 35 watts so hopefully your Provari is the Radius so you can up the power a bit. If not there’s still good stuff over an ohm, the Natilus comes to mind, the Uwell crown had an option for a 1.2 ohm coil if memory serves me which the 15 watt limit would handle. Anyway sorry about the long response and I didn’t really give you a proper answer due to my inexperience with high VG juice. Best of luck to you.
