I have also found that if I continue to "draw' after releasing the button, sucking the last of the vapor out, it reduces the condensation that has a tendency to build up, and get into your mouth.It's really going to depend on coil size and placement. I get 0 spitback or juice pull with my build, and it is my daily driver.
I think the condensation also "drips" back down to the wick, and then blows up and "spits" when the coil heats again .... I think it helps to reduce the "spit" .. but that's just me
