okay im thinking of ordering 18g to draw and 27g to inject. i have used 18, 20, 22, and 23 to inject in the past. im not scared of the needle its ju8st i get in a rush and shoot the shit in like 10 seconds and i was hopin a smaller needle would make it so that i would be forced to spend a few minutes to inject, but is 27 TOO SMALL?
