Sustainability comes to mind, as does the idea that the sand does not last forever, of course they would need a sand supply to top up from wind erosion, etc.
So, what are they meant to do, what are the alternative solutions, the perception is that it is a very well run club, and would have made a well considered choice.
I am assuming they have not chosen bright, white Augusta type sand, but rather a sand that was a close match to the local sand in color, so what is the issue?
The only playability one I see is the heavier nature of the sand will mean they will play or require a different kind of shot.
