Reading the 8000 yard thread, and others, it strikes me that the 485 yard par 4 limit is probably too short in the modern age. Putting aside your desires for a shorter ball, or competition ball (hard for some to do, I know) should the USGA expand the par 4 maximum length?
IF the USGA decides to expand it, and assuming marginal growth or mandated topping out of ball length from here out, what do you think should be the maximum par 4 limit and the minimum length for par 5 holes?
Certainly, 500 is a mathematically convenient divider, but is that too short for current conditions? Even good club players can probably reach most 525 yard par 5's regularly in two, no? (280 drives/250 3 Woods) If you designed for pros, 550 may not be out of the question, but that seems unrealistic to me.
What say ye?
