If i'm cutting then go whey isolate. Any tasty brand will probably do. I go the Protein Factory route... it mixes so ez, tastes awesome and is one of the cheapest out there.
When I have any sort of supplemental protein drink throughout the day, its always whey to build muscle... the only time i have something different is right after my workout... i always go with a whey isolate only... do not use milk with it on a cut though, use water only...
