This is basically what I do, but i use TNKs custom camera set up. For the first half of the at bat, I will just sit in the bottom 3rd of the zone with my PCI and just stare at it, and right when it is released from the pitcher, you can pick up the break and where it is going. And react off of that. I still tend to chase low, but really helps me lay off pitches off the plate.
If I am slumping I will always take the first pitch, but usually I am looking to drive the first pitch into the gaps.
Also if I find my self struggling I will just play on contact, more forgiving with check swings, and for some reason when I feel like I am not trying to drive the ball, I tend to focus more on release points and break, and work counts alot better.
And never ever ever power swing.
