What do you tend to use? Cartos?
Well, you certainly wouldn't want to use a medical hypodermic syringe anyway. Way too dangerous. And I think they are a controlled item with a prescription required.
A blunt syringe of 18 to 20 gauge would be better.

I rarely use a drip tip. When I do its just to take a few drags to "unflood" a flooded atomizer. But, to me, the flavor and vapor are not affected by the larger hole.
