You, know, I can't say - I don't have the digital vape. In general, I turn the knob all the way up, then back down about 1-2 tenths of a rotation. I usually hit it as hot as possible - by varying the speed (or intensity) of your hit, you won't burn it. Basically, the louder the sound of your hit, the harder you're hitting it, and the less it will burn. So I always start a little slow, then quickly pull harder as the bud heats up... I don't know if that made any sense, but a lot of theory goes into the perfect hit; I swear I could make graphs...
