In my opinion, the easiest (and cheapest) way to control distance would be to limit the size of the head.  Back in the days of persimmon, there were guys who could hit it a mile but the small margin of error made bombing it a risk.

With giant heads, the bombers can swing for the fences without penalty.

So I'm curious what everyone thinks about the driver head's impact on the 10-yard PGA Tour increase since 2002 when the USGA and R&A drew the line in the sand (well, on paper anyway)?

Significant?

Would regulating driver head size on the PGA Tour make a big difference?
