I have recently introduced this feature on 2 of our holes with the potential to do 2-3 more dependent on irrigation throw.
I personally like the look and it has also been done in an effort, along with other changes, to establish our course as being different in a market place of very similar courses.
As the distance from the surrounds to the next tee on these areas so far is only minimal, I estimate it has added approximately 5 minutes extra when mowing fairways.
I am however of the view that if to achieve this feature you have to hand mow it, topdress it, apply agrichemicals and fertilise it often than it most definitely should not be introduced.
