Phelps ready to try out new freestyle technique

As quoted in the AP article: "You'll all have to see. I'm not saying anything until we unveil it," Phelps said with a grin when asked how he's tweaked the stroke. "It's a significant change. You'll be able to tell exactly what I did as soon as I take my first stroke." He's on tap to swim the 100- and 200-meter free and the 100 butterfly at the Charlotte UltraSwim in NC. Should be interesting to see.
