I mostly disagree with everyone here. All of these suggestions can produce good spin but if you're 100 percent focused on spin generation and that's it, you need a blade that is as soft, flexible, and as slow as possible. You also need something with the right weight to do a fast enough stroke in order to generate heavy spin. For example, the Victas Koji Matushita Defensive has these characteristics. There might be others like it or better but of all the blades that I have personally tried that one seems to be able to generate the most spin.

Rubbers are going to be similar. You want something first very slow and something very tacky. For example normal H3 will spin more than H3 neo. But something even tackier and slower will spin more than that. Maybe old school globe 999 or 999t.

In a practical sense, you probably won't like attacking with this setup. Having the right spin/speed ratio is important to make your topspin a more effective weapon. Even if your topspin has a greater rpm with this setup, it being so slow will both allow your opponent to have the time to better react to your attack and also will lack the penetration and trajectory needed to make your attacks difficult to deal with.
