I think of all isolates i'd get the whey isolate. Isolate IMO is just purer protein, meaning they take out some of the excess carbs and fats etc. If you look at proteinfactory they sell soy isolates, milk isolates, whey isolates, etc. That's just larger % of protein. Only drawback is that they get used much faster than regular whey. Some say it's good, i don't like it.
Big where are you in FL? I'm in the m-i-a right now.
