I may not use it in Coil, but I do use it as my primary DD job. I worry about it because I want to know what's best. Generally "gimp" implies some sort of large difference, or at least a mid-sized one, so I figured I'd ask for the math behind it. Turns out there isn't any.
It looks like the actual answer is that you all are playing with self-imposed blinders instead, which is fine by me as long as I got my answer.
