Our experience with the cheap Callaway Diablo Edge Driverwas certainly a positive one. Prone to a high or ballooning ball flight with his current driver, or tester was able to able to produce consistently optimal trajectory with the Diablo. Even better, the club was very forgiving, as off-center hits did not typically produce disastrous results. All offer more than adequate distance. Our test Cheapest Callaway Diablo Edge Driver, which was equipped with a factory stiff-flex, Aldila Habanero shaft, seemed much attuned to a smooth, slightly relaxed swing

Features and benefits of the Callaway Diablo Edge driver:
Superior face, high MOI, deep CG, better aerodynamics = the longest, most accurate titanium driver Callaway has ever made.
Fused Titanium in a 4-piece modular design produces the most weight efficient titanium driver Callaway has ever created.
High performance Aldila Habanero shafts are engineered as the ideal compliment to the Diablo Edge drivers
The Aerodynamic Body Design refines and optimises all edge transactions, reducing drag up to 8% vs. other 460cc heads

I was once again pleasantly surprised as Callaway continues to obviously be sinking lots of money into research and development, as well as quality control. The Diablo Edge in discount golf store is indeed a cut above the original. There's a lot of technology in this one, so don't let that "Christmas Ornament on a Shaft" look of the original make you shy about trying this one. Whereas I called the first Diablo Driver--"Callaway's Tribute to the TaylorMade Burner", this one continues in that vein, however, there's more than just a slight tip of the hat to Cobra on this one. Lest that begins to sound too much like a messy hodge podge of wannabe compromises, follow me here on this one.
