Hello Mark The thought of having dual usage for props in the bank is a great suggestion. In a recent discussion about that same subject, Sterba was quoted as saying "He would add the second pattern to his props, but not to other manufacturers props" Liability was the issue. Having said that, he must agree that it can be done. The only question that I could even dream up is whether it matters how thin or thick the hub area of the prop is, and if for example it would not be recommended for a prop with a hub of less then X inches.
