While the new strains may be better to work with in many ways I can tell you the feel and roll is not as fun. Haven't played Oakmont in about ten years but those old poa greens were the best. The ones at Pine Valley and Merion weren't too shabby either. Kudos to the superintendents that have watched over them over the years.
Obviously the thoughts of Mr Solow ring true on this issue also but if you could just clone the Oakmont poa we all might think differnetly!
Archie, it's interesting you mentioned those three as PV and Oakmont still have their original (contoured) poa greens, although the rootzones have been heavily modified to help them drain better, whereas Merion has been bentgrass since the 90s (and before the latest redo). So is it the turf?
I guess that debate can be answered with Winged Foot and Baltusrol as they rebuilt their greens using GPS grading to put them back exactly and they used the turf that was removed (poa in WFs case and poa/bent in Baltusrols) so it will be interesting to see if they still don't feel the same as the only difference is the rootzone.
Saying that, I get what you are saying but is it coming from the fact that in these renos the greens are taken back to their original shapes and sizes and therefore give the impression that they are different? (Any slight grade changes to provide more pin positions not withstanding). Is it the receptiveness from the different soil bases? Or the putting quality? Healthy Poa is argueably a better putting surface as it typically has an upright growing pattern, whereas bentgrass prefers to lie over (hence its more susceptible to grain). However the window where Poa is at it's best is typically small as it's either going to seed or struggling to stay alive due to heat stress, where bentgrass - when managed correctly - gives a consistantly good surface all year. So is it something quantifiable or just the fact that it looks different?
On a seperate note, PSU has for decades tried to create the perfect poa but while they have gotten close, ultimately they were not able to get a plant/seed that would provide consistent results. Poa annua is an extremely adaptable plant so the modified plants quickly changed in their new envirnoments resulting in a different plant to what was seeded. So while its not a real problem to clone Oakmont Poa, getting it to grow in a different envirnoment would be a challenge and it quickly would become a different variety of Poa.
