I play with PCI off because I dont like having the graphic on screen, that bracket PCI seems like a great compromise. I didnt care for the old oval, but feel the last one that was speckled and not very transparent was bad. The effect and idea is ok, and some enjoy it, but I tended to turn everything off, including meters,strike zones, hot spots, pitch call out to simple...I like that these elements all received a fresh coat.
I may end up using that bracketed one during Spring Training and when regular season rolls in switch to no graphic again.
