Hey Bob, I usually do spares with a mix of hickory/apple or hickory/peach, and love them! As far as the dry chunks, you might try putting them in a sealed plastic container with a wet rag in the bottom for a few days. They don't need to be on the wet cloth, just in the same container. Wood will absorb moisture pretty quick if it's that dry. Soaking them for an hour or so is another option, just let them dry a bit before putting in the smoker. Wood in these don't have to be as moist as required on a stick burner.
