Different Bentgrass Greens

I thought you would find these photos to be interesting.  The turf variety that we used on the red and blue greens in 2006 and 2008 was A1 bentgrass.   It was the state of the industry at that time.   In the late 90s when NCC did the white nine, L93 bentgrass was used on the white nine. because it showed the most promise in the research trials.  Today, Pure Distinction bentgrass is one of the highly performing varieties that Bob O Link recently used on their greens in their renovation.  Just one of the characteristics of Pure Distinction is that it has an earlier green-up.   Each of these 3 bentgrass varieties has different growth and putting characteristics.
