Got my samples in the mail yesterday and have finally tasted all of them. All of them were 1 and 1/2 scoop samples which I mixed in water.
Texture - 10, no clumps, went down smooth.
Mixability - 10, mixed well with just a spoon
Taste - 8, tasted very good, but not really like cookie dough, would most likely taste great in milk.
Chocolate Peanut Butter
Texture - 10, no clumps, all good.

Texture - 10, all good.

Cookies N' Cream
Texture - 10, good as always.
Mixability - 10, as always.
Taste - 8.5, very similar taste to cookie dough, maybe slightly sweeter.
Texture - 10, perfect.
Mixability - 10, mixed instantly with water.
Taste - 10, really didn't think I would like this one too much, but it tastes great in just water. The other flavors would probably taste better with milk, but the fact that it is very good by itself gives it an extra boost in the taste dept.
