^^^You definitely got a FR Shock.
I just threw the Shock (2nd Run) for the first time tonight. It was pleasantly overstable, about one notch above the Volt, for my power. I couldn't get it to turn for the life of me, and it would S back nicely out of anny lines.
I'll probably stick it in the bag for windy days, but with my arm, it's not going to get regular use. Between the Volt, Tensor, and Zone, I have pretty much every overstable shot covered.
