Presumably, you are reasonably competitive on your own course.
This is a reasonably common 'problem' for someone brought up on a relatively easy course. If there isn't sufficient danger, an open course encourages smashing Drives, which can cause problems on courses that are more punishing.
One solution is to focus on keeping drives on the fairways - that is a pretty transferable skill. Another is to play other clubs as often as possible.
You're right about the Driving, home course being in the middle of a racecourse doesn't have a lot of trouble. I will take your advise, concentrate on the drives and play more courses, cheers.
