I guess I am more than anything against anything artificial as part of a golf course [think pristine links conditions and add only essentials from there].....less is so much more if you can do it.
And I'll say you can't simplify to that.
Who sees the liner?
Are you still as delirious as you said from your initial response?
Why do you recommend the sand get replaced every 5-7 years?
Dave,
We used 100% liner to keep the contamination out of the sand.
because we get lots of rain
we weren't trying to save money
we don't use mechanical rakes
we used a hell of a lot of staples - the recommended amount - which is rare and probably leads to more fabric failure than anything else - none of Ian's freeze concerns here.
If the guy on the bunker rake doesn't get told to race like it is the Indy 500 you should be ok
