Whey 17 has three flavours. Chocolate, peanut butter, and plain. They are clean tasting and not over powering. Surprisingly good in just water. I like to mix a scoop of chocolate with a spoon of instant espresso powder.
I also use optimum nutrition and mix extreme milk chocolate and French vanilla together about 50 50. It tastes great. Bodybuilding.com has deals sometimes where you can buy two 5 lb jugs and get a great deal. Their shipping was fast also.
