I used to have HELLA hang - with switching to rotaries I had to change that, I found that turning it down and having a nice 3.5-4 stroke with not a heck of a lot of hang, really helps me slow down, oddly it made me tattoo faster. I run my machines much lower than others seem to (not all), and it makes you slow down your hand speed, it also allows smoother blends more first pass tattooing.
