What Ball do You Use?

I would like to know what is your favorite ball to use?
I have been doing some experimenting with different balls this year. I'm trying to find one or two that work the best for me. So far I've tried the following balls: Titleist ProV1x, Titleist ProV1, Titleist NXT Tour, Nike oneblack, Bridgestone B330S, Callaway HX Tour. The one that has produced the most distance was the Callaway HX tour, with an average drive of 286 yards, a close second was the Bridgestone B330s at 284.5 yards. In all fairness though the weather was much warmer when I used these two balls, so I will have to use the others again and see if there is a difference. I use a Sky Caddie SG2, I mark the spot on the tee box and then hit my drive, go to my ball and mark the spot where it stopped, and my Sky Caddie gives me my distance too easy. I've played the Titleist for a long time now and I like it a lot, but I want to know if there is a ball that works better for me. I haven't used any of the so called distance balls yet, but the season is young and I have plenty of time. What do you think, what ball do you use?

Stay Stacked: by Rick Smith
"Don't let your left hip slide forward on the downswing, causing the weight of your body to drift to the outsides of your feet. If your weight drifts, you lose stability and power. Imagine you're swinging on a sheet of ice: You'd have to keep your weight centered over your feet. Focus on the feeling that your torso stays stacked over your feet.
