I think that there are always going to be stuides that disprove studies that disprove other studies, etc. I'm a believer in Dex/Whey PWO, some are not. But when you look at both me and someone else who follows a different path-- we both inevitably reach our goals. That's why I don't stay close minded and dismiss other's outlooks. Those who do that are too close minded and ignorant to see a bigger picture and to realize that there is more than one way to skin a cat. Unfortunate yes, but people are people.
IMO the only good thing about abc is the lists of exercises.
