One way to short change the outcome of your flooring project is to use inferior abrasives. You can have the best flooring, finish, and sanding equipment in the world. If you use garbage abrasives however, it can all be for nothing. Do yourself a favor and give 3M a shot at your abrasives business. It will be the last time you spend thinking about abrasives. I'm sure you have better things to do with your time.
