First stop: the driving range. I hit the five new balls, along with Powerglove.com's illegal Raiders ball-it's heavier, increasing distance-while Sean clubbed scuffed-up range balls (my idea). My hope was to outdrive him, at least a few times. Never happened. Sean consistently launched lopsided balls 340 yards, while my longest drive, with the Raiders ball, traveled 291 yards. Next it was off to the course-nine holes with each new ball, nine with each old one. Along with distance, I tracked greens hit in regulation, putts, and score. Here I saw dramatic differences. The Callaway HX Red, for example, lived up to its fly-farther billing as I knocked one 311 yards. The two other distance balls, the Top-Flite XL3000 and Titleist Pro V1, also landed farther from the tee. The Wilson True and Maxfli A10, meanwhile, both designed for control, hit the green more times in regulation.
