To me it seems that a wider drip tip produces way bigger clouds but slightly less flavor and a tighter one produces really good flavor but you won't be cloud chasing with them. I used to use tight ones cuz I used to use nautilus but now I prefer medium to big. Kanger subtank mini and bigger. I like wide bore on rda's, but it seems like its too much on the Atlantis v2. Your preference will be subjective
