Has anyone else done some quick drop tests to see how feeding goes on your modded one, like TF did? I was just messing around, I can't touch his numbers, but definitely seems to feed better/smoother than un-modded. With 85 balls, It would usually take about 8 shakes til empty. A couple times I got like 5, and sometimes I only get 7-8 balls or so per shake until the hopper is about half empty. Although, I did try a little shake/tilt around every second, to mimic like you're shooting/pumping/AT'ing, and it feeds that way consistently til empty.
I think I may try to sand down a real small amount more around the area that the insert used to be snapped into. Seems like it's always three or four balls that come into the middle at the same time and hold eachother up from feeding.
Thanks!
