Stuor 20 Gold Carbon

Just bought this blade to exorcise bad feelings after a drubbing in the local league. Asked for lowest weight, and received 86gms. Head dimensions are 157*150, ST handle 101mm. The pattern of the handle hints at the Butterfly Harimoto ALC but head size indicates Butterfly Inner Layer. Blade frequency is 1399Hz so this is Off territory. No idea what constitutes "gold" carbon but I guess is superior to bog standard stuff. Finishing is very good with a noticeable attempt at sanding the wings. Feels very comfortable in my XXXL hands. Will update when I decide on FH and BH rubbers as I ams transitioning back to inverted after a flirtation with short pimples for a couple of seasons.
