What protein powder tastes good mixed with decaf coffee?

The GNC vanilla whey powder is fine for coffee. I make a coffe latte every day (yes, I drink about 6 to 8 ounces of caffien) and ad about 4 ounces of nonfat milk and a heaping tablespoon of vanilla protien powder. So my coffee ends up having about 10 grams of protien.

I use 15g Champion Pure Whey Stack choco + 15 g IDS vanilla cinnamon.

The heat cannot exceed 160 deg, which is normal coffee pot hot. Not espresso hot or red button on the cooler hot.

I use a hand blender or Moo Mixer

I have used either vanilla or chocolate Body Fortress from Wall Mart - cheap and great as long as you mix it with a little water before adding the decaf coffee.  Use  milk and splenda as needed - I don't use either but that is each to her own.
