HSB will help a lot to control GSF reproduction. The more HSB you have the more control/ predation you will get. Start with DD1 advice of 10-12, but remove at least 10-12 more CC first. Use numbers of GSF young (3"-4") present and in traps as your guide to numbers of HSB.
GSF readily enter fish traps placed in shallow water. Build yourself a little larger fish trap 16" dia cylinder or similar box trap. IMO if you want to stock HBG for good survival with your existing CC (1.5 lb, abt 16") then stock HBG at least 3" and better use 4"-5" stocked ASAP.
If these HBG are fed daily expect them to be 6.5"-8.5" by October. Fed twice a week in a crowded CC, natural food shortage pond then expect them to be 5"-6.5" by October. Focus on removing as many CC as possible before adding HBG.
When you feed the fish you should be able to get a fairly good idea of how many CC you have present.
