so I got a hybrid of redcode with this setup: tecnifibre redcode 17g mains at 57 pounds prince synthetic gut w/ duraflex 16g crosses at 59 pounds. I didn't get to fully evaluate how everything played but i basically just got a feel for it. 2 things that really show up: 1) lots of power, even at 57 there was good enough power for volleys and such. Haven't hit full on groundstrokes but I imagine they'll be deadly. 2) big sweetspot! It might just be because i hybrided it, but the sweetspot is much more generous then my last string job ( kirschbaum competition at 57). I'll be updating this review with a more detailed response, as well as evaluating how it plays in maybe a week from now.
