120% WR for a pre-spawn F1 doesn't sound as good as it should be to me.
Lots of dense habitat will provide 2 things-good amounts of survival of small BG and ambush points for LMB.
BG, GSH are the only forage fish if I read right? And, they need to be available at all times in all sizes. Some other forms of correctly sized forage would probably help, and less competition for each.
I think I would strongly consider some threadfin shad as another alternative in your area, crawfish could be another option.
I think F1's will grow 2 lbs +/- a year with adequate forage.
