teehjaeh,
I know you asked Bill but have you looked at
FinFish Silver by Ziegler. I do not have any experience with it but Brehm's, where I sourced my YP, switched from AM a few years back and said they were going to stick with it. Stated they were seeing better growth. It is a 40/10 mix. Only problem I have is trying to source. There is a fish farm, Fin Farm, near Bill C. that carry's it but have not seen it anywhere else.

Ziegler also has a product called Koi Grower, specs are
Protein Minimum 42.0%
Fat Minimum 6.0%
Fiber Maximum 3.5%
The protein being up and fat being below the range you stated, what is the down side? I assume this would be better for older fish vs younger fish?
