Frank, not sure about your growth rates but I can tell you that the Lonestar Legacy LMB (From Overtons) were added to my pond one year ago June at 2 to 3" in size and the following March almost 50% of them were 13.5" and 2.8 lbs. That is not 2lbs 8 oz but 2.8lbs. And with your FHM's, they will move to deeper water this time of year and will be harder to see in the pond. Like you I thought mine were gone last year about this same time but when the water cooled down they showed back up. But I stocked 120 lbs in a 3.5 acre pond so maybe that is why I still have them in the pond. Good luck with your fishes
