It looks almost if not 100% pure GSF to me. I always leave room for that 1% doubt. Compare it to photos of D.I.E.D.'s GSF; Opps Dave pulled those photos. Sorry. Note how slender the body is, compared to that of a HyBG of similar length. Other features also signal GSF to me. Even on a strong slanted pose, note the distinct 3 defined emerald streaks on the gill cover - a distinct GSF character. The fish in the above first-link-photo is large because of the crowding of LMB in the pond. Few GSF are surviving and survivors grow well to large sizes.

PS - If only a couple more "10 bass stringers" are removed from this "APPARENTLY" bass heavy 0.5 ac pond, expect the GSF to become much more numerous and they will also become significantly smaller as average sizes. A noticable tip in predator-prey balance may have already been done with the removal of 10 bass from just a 0.5 acre stock tank. The presence of at least a few 15" LMB in a bass crowded pond indicates to me that the pond is not severly crowded with LMB. The LMB may be somewhat crowded but not severely.
