GShad if used should be delayed until 70% of your LMB are 18 in or larger. GShad can outgrow the ability of LMB to control them.

GShiners would be a good addition and FH are good to start.
GSH as initial forage will do a great job of helping your LMB reach that 18" mark (especially at lower bass stocking rates as ewest mentions), after the Fatheads get them big enough to eat adult Shiners.
