Only having seen the course twice, once on a calm day and once in a prevailing wind, I am inclined to score it between a 7 and 8.
At first, I bought into the notion that Troon only has good holes from 7-12. However, on repeat plays, I really appreciated holes 13-17.
I will agree that the start certainly leaves something to be desired, but they aren't bad holes per say, just not very interesting. That said, holes 7, 8, 10, 11, 13, 15 and 18 all make up for this lackluster start.
