So... I'm kind of new to the whole supplement/protein shake thing, and I've been using Myoplex lite for my first five weeks. It seems to have been working well. I love the taste and I've lost some weight and am gaining more definition etc. But lately I've noticed that a lot of people on this site seem to opt for optimum Whey 100%. It does seem to have a lower calorie/carbs/fat content. Should I make the switch? Is there any reason not to?

I use the Optimum and I like it. I've had the Tropical Punch and the Strawberry Banana Flavors, both of them taste decient with water and mix up well with a blender bottle. This is all that I've used so I can't compare it to anything else but I'll buy it again.
