these comments are all good. and i do agree that casting the fins would proably be easier than cleaning and rebuilding the real ones. i just have not done it yet. i assume that once i do i will not go back. but for now i still use the real ones. the fish i have entered into the 2 shows i have went to, have done well. not great because of anatomy placement, that I'm still learning. but not one of the fish judges marked me off for shrinkage.
