So I've been feeding Optimal Signature Series for the past 1 1/2 years that I purchase from the local fishery at a cost of $50 for a 45lb bag. The local Yardmaster store, who is a Texas Hunter distributor, sold me two bags of Sportsman's Choice for $25 for a 50lb bag.

The Optimal analysis is:
Crude protein 42%
Crude fat 10%
Crude fiber 4%
Phosphorus 1%
Ash 8%

The Sportsman analysis is:
Crude protein 36%
Crude fat 4.5%
Crude Fiber 6.5%
Phosphorus 0.8%

Is there enough difference to justify the cost of the Optimal?

What are your thoughts?
