protein efficacy question

i see it as a timing issue. the hydro's, pp i use for when i want a rapid amino surge ie pwo. the bio, cfm etc for mrp's when i just want extra protein intake. caseins, milk proteins for a more prolonged release. the plasma i see as an addition to all proteins to enhance the immune system. thats my reasoning for using different proteins but i'm sure others opinions will vary

I agree. The type of protein you use should correlate with its purpose. Once you've nailed down what you plan to use the protein for, then you can narrow your choices further based on your desire for performance versus taste and mouthfeel, and a variety of other considerations.
