I don't have to own the 20-position wheel to tell you that it will have all the same downsides as the original fx powerwheel. Phil's micrometer is the only upgrade to the fx power wheel worth doing -- and it does it right. I was concerned about the micrometer's thimbal accidentally moving, but with normal handling it has never moved unintentionally. There is a fairly snug o-ring inside of the micrometer to keep it from free-spinning. If it's not enough resistance for you, then you can add a 2nd o-ring. I've had no need to change anything about Phil's micrometer mod.
