The Dr. Kracker ones, if you can find them, are like 1/4 inch thick bricks, they're fairly large to start with, not easily crushable. Sometimes a corner will break off. So much of my standard trail food is mushy, I appreciate having to crunch into something. The Sesame sticks, I expected to crumble, and they did break, but still into useful sized pieces. From a pure envious looks of other hikers value, these rated high.
Fritos, I tried to save to mix in with my meals in the evening, again, just for some texture.
