I definitely believe in using them. Both seem to perform similarly. Slab bites will dry out faster than Crappie Nibbles (not in the jar, but when I keep a few out on the boat. Crappie Nibbles seem to be more of a dough and Slab Bites feel a little plastic-like (especially after sitting out in the sun for a few mins).

Anyway, onto the actual question. I've noticed that when finding a bed (and catching several fish), there will be a few slab bites floating around and nothing ever comes to eat them. Crappie Nibbles don't float, so it's not as obvious, but I've tossed them out to fish I could see and they don't eat them. I don't even see them taste them and then spit them out. They seem to ignore them once they've just "sat there". Perhaps the fish just need that movement to get them interested, but I just expected the fish to gobble them up.

Oddly, if I drop a tiny treble hook with just a nibble, I can catch all the tiny bluegills I want for catfish bait. Also, bluegills are notorious for hitting the moving baits and "stealing" the crappie nibbles off jigs and small spinners.

Anyone else notice this behavior and have any thoughts on "why"?
