Powdered Gatorade & Carbo Pro. I just read an interesting study, to summarize; although some carb/protien sources may have a slight benefit over another, if it tastes bad, you won't drink as much or as often and therefore negate or relegate any benefit. Drink what you like so long as it gas a low osmology (absorption rate) and provides carbs at a rate of 200-300 cals/hr.
