I've torn up my share of props on my boat and will tear more up before too long. On my boats, the same as my turkey guns, I play with different wheels to get the best performance out of them. Every time I replace a prop it never performs the same as the prior one, even though it is the same make, model, size, and pitch. I always think getting a good prop has more to do with luck and black magic than math and science. Now on to turkey chokes, I own a few different chokes for a few different guns, but I have never tried two of the same make, model and restriction on the same gun. If you have, is there a difference or is the performance the same? I would think it should be the same, but would not be shocked if it wasn't.
