Callaway continues to champion its popular metal woods with its new line of Big Bertha fairway woods. The Diablo series contains stainless steel construction, neutral or draw designs and the company's signature and trademarked S2H2 weighting. The 3- wood (16 degrees), 5-wood (18.5), 7-wood (21) and 9-wood (23) come stock with a mid-torque Callaway graphite shaft available in light, regular and stiff flex. Diablos are also available in a neutral-weighted strong 3-wood (13 degrees), strong 5-wood (15) and strong 7-wood (18).
Each club in the Diablo series produces long, fairly low trajectories and picks the ball off the turf very well. They are comfortable at impact on solid shots. Head weights are balanced nicely and tee shots are accurate and long, with the strong-3 being the best performer.
Diablo draw-promoting designs can produce hooked shots on mis-hits and fast, hard swings. Much like the Big Bertha Warbird fairway woods of the past, the new breed might also prevent the average player from getting the ball up, especially off the fairway. Clubheads are on the small-side, which might limit confidence at setup for novice golfers.
Callaway Big Bertha Diablo woods, for the novice to advanced player, are superb performers. But they fall slightly short in being true-game improvement clubs for the occasional golfer or weekend- warrior. Each club falls around the $150 to $200 price range (2009).
