Whats your favorite blend from True Protein?

Im about to order some more protein and im thinking about the recession bags good price for sure about 5 bucks a pound. ON at gnc comes out to like 10 a pound lol its commical. What is your favorite just isolate? Concentrate? The ultra whey blend is what im thinking about going with kinda the best of all of them in one

ultra whey is good...

but I like isolate the most

do you take isolate all year or just dieting? I might get the isolate now that i think about it just because im dieting.
