Consider getting and reading the last two issues of Pond Boss Magazine where Sprkplug (Tony Livingston) has two great articles about growing HBG. 2014 May-June "Hybrid bluegills .... Benefit or Boondoggle?" and Jul-Aug "Art of the Science of Growing Huge Hybrid Sunfish". Good how to articles.
We assume that you have read these threads from the PBoss Forum Archives? It includes pictures of some of Sprkplugs HBG.

As mentioned pure strain BG will soon outpace the reproduction of HBG. Then if this does not work draining and or chemical renovation is still an option.
If you are going to feed pellets and want additional tackle busting excitement, then consider adding 10-16 HSB into the HBG mix and reduce a comperable number of stocked LMB by 10-20. I doubt you will regret using this option. As HSB are removed or die replace them with 6"-8" HSB.
