IMO if your goal is just supplimental feeding then GFC is good for BG although the smaller GFC pellet size I think is larger than that of AM400. To get a little more value of AM use AM500($32-$34/50 lb = $0.68/lb) which is a pellet size similar to the smaller pellet of GFC. IMO BG in similiar conditions will grow faster and eat more on AM compared to GFC. A techincal study would have to prove the differences. Several studies have shown 32% protein is adequate for BG growth. Truth be known overcrowding and social structure balance of BG probably has more affect / influence on BG growth than the protein difference between GFC and AM.

If your pond is larger and you are feeding hundreds or a 1000+ pounds per year then cost could be more important depending on your fishery budget. Since I only feed about 150-200 lbs/yr then for me the cost difference is minimal.
