Go to a typical outdoor store and the selection of "energy" bars is overwhelming. I wouldn't know where to start.
Grab one of everything, and eat them for lunch/etc. (Preferably when you are within 50 yards of a toilet). It is really nice to learn that something doesn't work for you while you are in civilization. Take notes.
Do the same at walmart. (I mean buy a bunch of bars, not try a bunch of bars and use their toilet).
In any case, I much prefer to have a variety, rather than a whole case of one kind of thing.
I pretty much hate cliff bars. Something about them tastes like chemicals to me. I end up with a mix of nature valley (rock hard "crunchy" bars and the other ones), Kind bars, superfood "meal" bars (ha!), snickers, protein bars, a couple power bars, etc.
