I try to be a planner but some times the bomber in me wins out
Me too. The last time I played a new course I looked at it ahead of time and had a pretty good plan for how I was going to play it but half way through it I decided just to play driver the tee to make it more interesting.
Though to answer the original question I know for sure strategic planning helps me when I stick to it. I have a very solid plan for my home course where even though it is a harder course I shoot better there because I follow my plan and rarely take stupid risks.
