Charlie, I throw Cargill year round. IIRC, the various numbers are pretty close to Purina Aquamax, but I'll check next time I get out.
Al,
If you are throwing Cargill, then it is most likely a fish meal protein. I throw cargill 4512 mixed with GFC. 45% protein and 12% fat. Not sure how that stacks up to other pellets. But I think I will continue to throw it this winter.
