General rule I use:
1. If sand is 15/20 then Irons will work, but be careful of your line cause flight path is very slow and if it's near lip, it will clip it!
2. 30/40 sand+ wedges only.
3. 20/25 sand, something in between:
general things:
4. all oakmont sand is 30/40+
5. alot of kiawah what seems is a sand it's not: it's dunes and has yard sand which can be played off with irons
6. bp 15/20 is fine for irons.
7. sta 15/20 is very rare, 30/40+ is wedge time.
