I would not suggest you eat any kind of soy protein, unless its fermented (tempeh or miso).
As for as supplementing in general, I'll be the first to admit to using protein powders to help my daily needs, plus I work 70-80 hours per week. But, being a holistic nutritionist I still think we need to eat whole/unprocessed proteins (not supplements) when ever possible. So, unless its SUPER inconvenient to cook/prepare your meals, just stick to good old fashioned food. The only place you would be lacking is around workout time. As it was mentioned, I would look into egg protein powder and its actually relatively fast digesting (but certainly not as fast as whey isolate or hydrolized whey).
Also, another note is that I love Metabolic Drive, but I started getting an allergy to it myself (which can happen with any protein powder). So, I'll be back to using it in the future, but I think its important to mention that we need to rotate our powders from time to time. This leads me to let you know that the over-consumption of eggs/egg protein can also create an allergy over time, so I would use it sparingly especially if you are eating cooked eggs on top of the powder.
