The flight control might be good for non-ported chokes. They were designed to be used in non-ported chokes. Ported chokes are designed to separate/strip the wad away from the shot so the pattern doesn't get distorted in flight. The flight control loads are designed for the wad to remain with the shot longer to keep the patterns tight. I tried them with my jelly head just for kicks and the results were less than impressive. Of course, every gun/choke is different, so you never know.
