You read my mind :) I did this today on kiawah (11 i think) as per a recommendation in a thread, it was a fairly flat and large green, helped me map out my pitches and the use of spin.
I am now looking at slope, ie how much to add or take off depending on the severity of the up/downhill slope.
As well as looking at impact of rough % on the lie, the other thing will be green elevation ie is it 2ft above my lie etc. Any tips on this would be appreciated lots.
So much to think about just for understanding one shot :)
The challenge is what makes it interesting :)
