Thanks for the link
I assume its Bermuda or similar but I can never remember even though I've asked more than once (its just not a detail I seem to be able to retain)
The growth being to the west is a good tip i didn't know (although makes sense since I was told the nap at one course was usually towards the clubhouse, which lies to the west)
I knew about the 'look at the hole' tip and used to do that but got out of the habit so hopefully re-reading it today will get me doing it again
On the dark/shiny tip, I just can't do it. I dunno if its because I always play in sunglasses or something else but its a detail I just cant see
2 day comp at the end of this month on a course with the toughest greens on the island (with the most noticeable nap) so reading that link is a useful refresh
