Just curious why you are afraid of wicks?
I think many people get frustrated with cartos or string-wicked delivery devices if they use particularly thick, troublesome flavors such as Boba's Bounty. I've come across a lot of vapors whose all day vape is Boba's and they require a new carto daily.
I've had a lot of problems with that flavor myself in a cartotank. It doesn't really matter how many holes you put in the carto (I've had as many as 4 tool-punched holes), it will still stop wicking well after the first tankfull.
I believe the issue is the notorious thickness of the 100% vg, but also that juice has a large amount of particulate matter suspended within it that doesn't get vaporized by the heating elements, accumulates in the tank and quickly clogs up the filler of the carto, rendering it unable to wick properly.
These types of juices require a wickless delivery system. I've begun recommending like-vapors to check into bottom feeders, the AMP tank or Killer atty, or the Vape Mate if they 'Vape for Boba's.'
