Man, you shouldn't have told me it was useless! All those beers over the last 5 years were crap then, and the awards were bogus.
Tell me what forum says this?
Seriously, you just have to understand the tool and use it properly. Promash has both Brix and SG when you formulate the recipe. You get used to looking at both and switching back and forth. The morebeer converter is good for the FG. I have been using a refractometer for so long, I would not go back to a hydrometer on the hot side.
