yea man its the way to go, throw almost any fruit in there and you have a total fruit shake, most strawberry wheys all taste good. If you want variety go with strawberry!
If you go with the vanilla, you can add sugar-free chocolate syrup and now you have chocolate protein; add frozen strawberries to the vanilla and now you have strawberry protein.
Try figuring out a way to turn chocolate into vanilla...
If you have a blender and milk or juice any of them will taste pretty good. It's when you don't have those things that they start to taste like ass. I've been forced to take my chocolate in water, and it's goddamn sick.
