I'd keep around 7000y. But I would design half the par 4s NOT to be mown/maintained between 280 and 330 from the tee apart from a 10ft wide walkway!
another misguided solution to avoid fixing the issue at hand (if one believes there is an issue)
Though I guess that's way to to get them to hit long irons (2 per hole in fact)
so everybody hits the second shot from the same place after hitting driver (if they're really Tour short) three wood, hybrid, or long iron.
Mike,
What would make you think the "USGA" would not allow distance to make great leaps forward-or more to the point that they have anything to do with yardage gain.
All the substantial gains of the last 20 years have been within the rules-all while the USGA consistently stated the yardage gains each year were insignificant.
Well twenty years of insignificance added up to 30-40 more yards per player
The manufacturers are leaps and bounds ahead of them, to say nothing of additional gains through optimization, fitness, lightness, lower spin high loft etc.
