Callaway offers physics lesson on the clubhead of its new V Series driver

By Mike Stachura

loop-callaway-vseries-driver-518.jpgCallaway isn't saying much about the Big Bertha V Series club that showed up on last week's USGA list of conforming drivers. But given the timing and some of the clues on the clubhead itself, you can make a good guess as to what this driver is all about.

Making the rounds on tour this week at the WGC-Bridgestone Invitational (Thomas Bjorn is said to be one interested candidate), the club definitely emphasizes less weight. You can see slight indentations in the sole that are reminiscent of the old Big Bertha Warbird sole.

Most telling, however, are the words and formulas emblazoned on the clubhead. Included is the phrase Speed Optimized Technology and the formula for kinetic energy. The latter is a clear reference to the importance of increasing velocity (swing speed) to generate more energy at impact.

The adjustable driver is available in three lofts, according to its listing on the USGA website (9.5, 10.5 and 13.5HT). The company plans to introduce the driver formally next week.
