Never hurts to have 2
tanks. I normally do Max VG but you may want to start at 65VG/35PG, in any sub ohm tank you want 6mg of nic and lower...trust me, not worth it to try 9mg you will regret it.
These are the ones I have tried -
On Cloud Custard - good custard, let it steep
S+C 2 - only tried the first version (which was good)
Peache Guavara - sitting here steeping haven't tasted it yet, but it smells fantastic!
Circus Bear - good stuff
Cowboy Cooler - awesome
Tiramisu - the best
