Personally, my favorite protein powder I've used, at least in the last couple years, is Dymatize Nutrition Elite XT (also known as 12-Hour). http://www.amazon.com/gp/product/B00...F8&me=&seller= I've gotten the Fudge Brownie, Banana Nut, and Rich Chocolate and all were really good. Banana Nut was the best.
I also had one I used to use in high school that was really good but I can't remember what the name was. If I see it, I'll remember, but can't for the life of my come up with it right now.
