I like TP blacks, and not just because I'm a TM man. I've tried my share of tour balls, I've experimented with pentas, pro v1s, mike tours, bridgestone tours, callaway tours, and I'm finding my self going back to the TP black. It's just a sheer performer. Good, predictable spin around the greens, nice feel off the driver all the way to the putter, and they're long. Not to mention the cut through wind like it's not even blowing.
As for the winter, I'm just playing whatever I can find. No point in buying nice balls when all of my winter rounds are pretty much practice preventing game deterioration.
