Sounds like a lot of the disappointment stems from (not wrongly) expecting the GB2 to be a direct sequel to the GB1. Other than being designed by the same person, manufactured by the same company/oem, and comprised of the same materials, they are essentially different knives.
I for one am highly satisfied with the Gayle Bradley 2. For me, it fixes the preference issues I had with the PM2, and checks every box for what I'm looking for in a large edc folding knife. The build quality and the price makes this knife a no brainer for my preferences (slim profile, no edge choil).
Btw, rexromic, I noticed you withdrew the GB2 from sale; What changed your mind, if you don't mind my asking?
