I am going out on limb here and suggesting that more pallets should be installed for your size of a pond. I say this because you have not mentioned (with extra surprise and delight) that you have gobs and gobs of FHM's in the pond currently. If you do, then ignore me, but if you don't...their reproduction has been less than what's possible. My 18 or so pallets in my 1/4 acre pond helped produce so may FHM's that I was worried that I would have a DO crash, maybe worried without actual need, but I was worried just the same. They were everywhere!
With that said, my stocking 40 HSB and 600 panfish (HBG and RES) had so many FHM's to eat that I did not have to feed more than 1/3 pound of pellets per day. The game fish were stocked one year after the FHM's. My HSB went from 4-6" long to 13" long in one summer. I expect the pellet bill to go up this year as the minnows have been knocked way down in numbers.
While you waiting for more experienced advice on stocking numbers...I think that your HBG numbers are a low and your combined HSB and HBC are a bit high. But, most of my reading has been done to establish a pond that hopefully generates larger HBG rather than bass or cats. If reproduction of your hybrids is low across the selection, you will need to feed pellets at a higher rate because you do not have much for forage production. I think you should at least double (maybe triple) the HBG number and mabye cut the HSB and HBC numbers back by 15%. That's my very NON-Experienced advice. I have thrown it out there to get the attention of others with more expertise who will correct my thinking if need be.
As far as stocking sizes are concerned...The HSB should grow rather quick and keep ahead of the others, but if you do not get your forage up initially or adjust your original stocking numbers you could put in the RES and HBG this year with hopes that they reproduce some to help with forage (YOY) and then put in the predators next year. For example, 2 to 4" Res and HBG this year and 4-6" HSB and HBC next year. The panfish will reproduce some this year and provide more breeders for next year when the predators go in.
Sorry to ramble on, but I tend to offer my 2 cents even if it's not worth one.
