As with my recent round at Merion's West Course, I played The Creek yesterday for the first time in some years and was struck by how really good green complexes don't need to stimp more than about 8 in order to be challenging. The greens were not even close to lightening fast (although they were firm), but they were still problematic unless you were underneath the hole.
Sidehill putts still broke 6+ feet, being above the hole was still scary, uphill putts required a good stroke even more than is now the norm and everything that the Golden Era architects intended is still operative. No clown's noses, no windmills.
Had the greens not been firm, much of the original challenge would have been diluted - fortunately this was not the case.
Like Easthampton and Merion's West Course, the sane maintenance meld on the putting surfaces was a treat.
As much as I admire much of the changes made to Augusta National over the years, the speed at which they maintain their bent grass greens for The Masters has not, IMHO, been their best contribution to golf.
