Wait 'til you're 67 like me. I'm definitely a shorter hitter now than I was at 30 something, but then I never saw the supposed added length that the evolving equipment was supposed to be generating. My first metal driver, a TM Tour Driver (9.5° with a 43" steel TT shaft) back in 1988 was still as long as any I've ever owned - I've never been able to figure out why. And that was playing a Titleist Tour 100 Balata ball. The equipment supposedly gets better, but I mostly stayed the same, even when I was still in my 40's. I just played my game and didn't let it bother me that much.
I still believe that the added length is as much a factor of the 2-3 inch added shaft length in the driver and the stronger lofts in irons as it is in the hotter ball. I cut my driver back to 44" for better control, so I wouldn't expect to see crazy distance out of it.
I played with a guy a couple of weeks ago that was 69 years old and he could consistently drive the ball around 280 yards. Not bad for anybody and great for that age. Of course I have no way of knowing what he did when he was 30. He was the longest "senior" (that I consider over 65) golfer that I've played with.
