What started this craze towards pure poa and what was so wrong with the old bent/poa greens that could be blamed on the bentgrass anyway?
Aren't design intent and approach-play variety just as important as putting? If yes, then how can an annual, notorious for its instability, be a good thing for either?
Apart from Oakmont and Pine Valley, how many of the top 100 courses have pure poa greens now and how many have bentgrass or bent and fescue infested with poa?
What does it matter anyway when you're dealing with a plant so genetically diverse in such diverse climates? Don't you treat every course's agronomic requirements on their own merits anyway?
