In the end, I'd say consensus should rule. You can't please everyone, but, especially in a cragging setting, you can (and should) try to please most people.
I ate pringles last weekend while skiing...they rule! Fat to keep you warm, and best of all, they make you thirsty, so you don't blow off drinking. And they're cheaper than GU, too!
Though I do use GU on big trips.
