the course i play alot generally has no one on it, so i can go play by myself and play 3 balls per hole, on a par 4-5 i will play both a driver and a 3 wood off the tee and then a 3 iron, then will take approach shots to the green from where each ball landed. On a par 3 i will play the right club distance wise, but try and aim for different shot shapes which will hit different parts of the green.
Im fortunate to play a course that is relatively quiet and doesent have many people on it. Everytime people talk about 6 hour plus waits, i think how unlucky they are. my biggest fear though is i will get a hole in one with no one there to see it :o
