Eric:
It's hard for me to feel I'm making valid comparisons; we know how much the same fish can vary from season to season, day to day, even minute to minute (with mood swings, etc.).
Anyway, FWIW #2 & #3 look like what I remember my HBG do (haven't seen one for 20 months). #4 looks to me to be the "most different."
What do you see as the chief differences between #1 and #5? I see the GSF-ish gill striations on #5 but not #1; to me, that makes #5 look more like #2 and #3.
