I looked for a thread on this and couldn't find one - apologies if this has already been beaten to death.
I'm all for it. After Stupid Trees, my other pet peeve is Golden Era greens that have become impossible to putt because they now "Stimp" at speeds for which the architect never envisioned would ever be possible. I have given numerous examples of this in older threads including Pine Valley, National, Shinnecock, The Creek, Piping Rock and Merion (including the 5th green along with #'s 12 and 15).
In the last 20 years, at least 1/3 (more?) of the 12th and 15th greens at Merion have become - well - ridiculous as the technology of both turf and mowers has made it possible for clubs to increase greens speeds way past the "red line". I've never been a great putter, but I've hit enough good putts at all of the courses I mentioned to know that the difference in playability over 44 years isn't just my eroding skills.
Merion's green complexes are wonderful just as they were designed. They don't need to be impossible in order to be top notch. The same can be said of the other courses I mentioned above.
Merion's much discussed, and much maligned, bunker project returned them to their original degree of difficulty as Wilson and, later, Flynn (others?) intended. I applauded that at the time and my opinion hasn't changed.
IMO, softening the pitch of #12 and #15 returns those greens closer to the degree of difficulty that Wilson and Flynn (et al?) had in mind. A good move.
Let the fur flying begin.
