I saw the ones with the balls in them at Boaters World on the display rack. I saw the discussion on baylinerownersclub.com too. Myflies, I believe, was the one who used them with success. I recently switched to them. I have had fantastic results. The 20' Trophy has a serious design problem with the scuppers being under water and then filling the fishwells. The rubber flappers are only good fore a limited time before they curl. My concern about the balls is how fast can they drain if you were to take a huge wave over the side in the ocean. I have not had a problem with them yet.
