Cba, thicker juices work better in nothing really. They are harder to squeeze out of a bf juice bottle, and harder to wick to the heater in cartos. Some juice is only available I. Thicker/high vg content, so you have to adapt you vaping to them. I am to the.point where i use only 306 style attys, and cherryvape drip tips, so I can see the amount of fluid in/on the atty coil. I give the bottle a squeeze, and a quick suck while squeezing, and i will have about 1/8" of juice above the bridge bass, this amount is good for quite a while, as the 306 has a built in reservoir below the bridge. Everytime you take a pull, it lifts the juice onto the heater. When the flavor thins a little, give it another squeeze and suck, and you are good to go again.
Just my method, ymmv.
