That is an easy question to answer in two parts. First you need to know how far you hit every club in your bag find a PGA professional that has a TrackMan and hit every club in your bag and find out how far they go you should do this at least once per year should cost between $100-$200 a session. Secondly especially on pins that are on the front of the green play to the center of the green shots coming up short being shortsided leaves to bogeys and doubles and you will improve greatly if you play towards the middle of the greens on front pins
See that was easy.
