If your just trying to score and not working on certain aspects of your game, then I would approach it on a hole by hole basis

1) how does the hole set up? is it wide open/tight, a fairway you should hit with either club, is finding the fairway important (not going to effect your next shot), what are the problem areas (left, right etc) can they be avoided with driver,

2) how confident am I in each club. Because if your not confident then you have problems.

My advice go in with a set plan, pick some of the more wide open holes and hit driver see how it works and evaluate from there.
