Don't wait until you get the dry hit to feed your carto, you can feed it a little every few hits and keep it wet. Nice thing is if you over feed it you can set it down for a few minutes and it will drain back into your feed chamber and down to the bottle. If you tilt the Vmod up as you take a hit it will feed itself. The only time I find myself squeezing the bottle to feed is after a bottle gets less than half full. I agree with corruption42 attys are the way to go and the Vapage Slant Coil in 1.5 or 2.0 ohms are great.
I tried the carto first and got sick of trying to figure it out while inhaling burnt hits. Switched to the atty - have vaped with it for two days up until tonight when I gave my rba a turn on another mod. Now I don't see the point of using cartos with the VMOd since I can vape continuously with an atty anyway. Nice flavor with the atty too.
