SeaDwarf and Platinum are among the best varieties for fairways. SeaSpray is also good, but can grow upright if not mowed low. I suspect one of the reasons Jay notices a grab is the amount of care afforded to the turf to make it green and appealing to resort guests...Americans. When Paspalum is properly watered and managed it takes on all sorts of off colors. With a sand base, it will be fast and firm unless allowed to thrive and grow upwards between mowings. The balance is just enough water with regular mowing during the summer (growing) months. No paspalum I have ever seen is grabby during the winter (dormant) months, or any time either side of those months.
Thatch is also an issue. Just like Bermudrgrass, Paspalum requires verticutting and management to reduce/eliminate thatch. Thatch allows bounce and takes away the firmness. This is common on courses where maintenance gets rolled back...Mexico would be an example as it has experienced less and less play and, therefore, prone to cut-backs in staff.
At Olivas Links in Ventura the management is increasingly aimed at less water and fast and firm. And, there is plenty of whispy native grass there despite Adam thinking it was all hoarded by the Brits and Aussies.
