Vertical purplish stripes are common on northern BG in the 4"-7" size range. IMO coloration of #3 is spot on for northern BG. Mouth size on #3 is also characteristic of pure stain BG. Also in my experience for #3 notice how long and pointed the pectoral fin is. I have done lots of fin measurements. The pectoral fin posterior almost and often actually reaches the front or 1st spine of the anal fin. This never happens with a HBG because the pectoral fin of GSF is short and round. Pay attention to this when you see BG, HBG GSF. RES pectoral fin is also as long as or longer than that of a pure BG.
