I cant handle any of the mix's that have protein in them, especially on a hot ride. So now i use heed which ive never had gastric problems with, and get my protein with food.
I'm a big fan of the orange flavored Heed. My advice for the OP would be to try stuff out on shorter training rides -- don't make a long ride your first experience with something (that goes for food or beverages).
You'd hate to find out something gives you a sour stomach part way through a century.
Like Jarery said, the drinks with protein (SE, Accelerade, and others) don't sit well with some people. Experiment, and find what works for you.
