First post here, but I noticed you said your new tank leaked on you the other day at work. I own two tfv8 cloud beasts and whenever I top off my tank with juice I put the cap back on, then turn the tank upside down and rotate it 360 degrees once or twice. This eliminates the dreaded leak you sometimes get when refilling a subohm tank/RTA. I do that with all tanks/rtas and it really seems to work.
Also, I am gonna say give squonking a try. For $40-45 you can pick up a Pulse mod kit with 24mm RTA. I know a lot of people knock the pulse, but I love mine. I have that mod with a 24mm dead rabbit, running a single coil 24g kanthal parallel wire 3mm id 5 wrap. The flavor is awesome, clouds are decent too. I run it with 18650s and I only change the battery once a day with heavy vaping.
Hope you find what works, I know what a bitch it can be trying to find the right wicking/coil combo on rtas... I have two geekvape Zeus tanks that I gave up on recently. I think I'm going all squonk soon.
