Actually I don't know many pond managers that recommend waiting a year for bass. In the case of FHM, a year isn't going to matter; the bass will still eliminate them within a few months or less. With bluegill, they don't need a year because bass will never eliminate them and the year is not only superfluous, but they'll very likely overpopulate the pond in that time such that it will be difficult to get it righted again and could take years to do so short of Rotenone. If Cougar cared only about bass, it wouldn't matter that the bluegill were overpopulated, and it could help the bass; but since he wants good-sized fish of both, it would be highly counterproductive to wait a year to stock the bass.
Along those same lines, 100 bass is too few if he wants good-sized sunfish as they won't be enough to keep the sunfish thinned to the point that they grow to good size. 200 should be enough.
