Hi,
I'm really not a 'big hitter' - but I've always been pretty consistent/straight.
One of the best purchases I made last year was a 'clearance' Cobra SZ 460. I used a Calloway Biggest Big Bertha (I think the original one) for about 10yrs leading up to that, and probably averaged 240 - I could maybe get a touch more from time to time. But WOW, these big head/sweet spot drivers really work! I'm getting the same consistency, with 20 extra yards and more... I'm about 5-6'' - so I feel like a cartoon character with this thing!
I joke with my playing partners that I have 'embraced the technology' - don't fight it... They just roll their eyes..
Jim
