The mixed lengths helps fill that gap currently, but if enough people prefer a single round pellet in an intermediate size we can certainly make that happen. Our standard bluegill feed will work for pretty much all common pond species.
Over the years I've recieved pretty evenly split feedback on how well the 9mm works in feeders. We sent all of our diets out to texas hunter in the early days, and the 9mm was determined to be the biggest size it could throw without issues. I think that maybe the humidity in some places might cause them to swell a bit and cause jams.
Species large enough to eat the bass feed diets would likely benefit from the higher protein and lower fat levels, so I anticipate they would all do well on it.
