The glo I got has a higher shoulder but flat top, pearly as all get out and the ghost stamp is super cool. I found it to be a very neutral Buzzz OOTB, played half a round during lunch at DGGW w/just the glo Buzzz and a Soft Wizard. Def not a lightly-concave low-glide power hungry HSS devil like my stock glo Buzzz. Flew pretty much like a longer version of my lightly seasoned Wiz, some turn, good glide and fade if it had the height and time. My buddy was throwing my dead-flat stock 10y Buzzz and a fresh Wiz out of my bag - definitely more HSS on both of those.
I didn't get to hand pick it, so idk if there were flat/lightly concave ones like the usual stock Glos in there.
