I would stock the FHM as soon as possible, 2 pounds should be fine.

Next spring go to your local bait shop and see the condition of the shiners they sell. They should be golden shiners. If you are unsure, buy a dozen, take photos and post them on here for ID. If they are golden shiners and they look to be in good condition, buy 5 dozen of the 3"-5" ones and stock them. Give them a chance to spawn, in that area, they should have pulled off a good spawn by the end of June.

Try to source smaller CP, say less than 8". Then stock 10 of them from late summer through early fall.

No need to stock anything else if CP are your total focus.
