There are a few things left to discuss but the site really has no interest in discussing them for good reason.
For example: let's discuss the Toyotas and Hondas of golf ocurses and how they are designed condtrcuted and sustained instead of always talking of the Mercedes, Rolls etc..
How bout this one: will the jagged edged bunker concept stand the test of time in non sandy soils?
and another: if you were going to learn to shape, would you prefer to learn in sand or clay and heavy soils? And, which is the easier to go from and to?
