I didn't trudge through this entire thread but I have something for your consideration.
Most will agree that quick absorbtion is an advantage in post-workout nutrition. You would do well to consider the fact that protein stimulate within the gut the release of cholecystokinin (CCK), a chemical wich retards the rate of gastric emtying (the rate at which your stomach empties into your intestines).
This effect is most easily controled. By using carbohydrate at a rate of 4:1 in regard to protein, CCK is kept in check and nutrient absorbtion rates are kept near optimal.
