I'm still overhauling the Super Jolly, so it isn't in commission yet. I'm hoping to finish it up today......now that I have the extra motivation. But I totally agree that using the actual commercial grinder will be a big improvement, especially having a doser. When I'm just wanting to pull 8 shots in a row, standing in front of the Rocky for 30secs at a time kills my flow.
If you lived closer to Dayton, I would bring my MM over with a freshly rested batch of home roast. Love to try a commercial machine with my own concoction. I am sure it would be quite a humbling experience, especially after the first pitcher of bath bubble milk.
