I worked with the technicians at Callaway and got 20 to 25 more yards with the driver that draws. My normal driver is like a 3-wood. I needed (the extra distance) to combat the added length. This is probably the only course I'll do it. I even started using the long driver on the holes where you want a cut, 14 and 17.  -   Phil Mickelson     Quotes
