A solid piece of advice about mapping, 4wedge!
If I may add some, I always map based on fairway shots. Then, I account for tee shots going about 2-3 yards farther than fairway ones.
In my opinion, full backspin should be used cautiously, as it tends to do more harm than good, especially in strong winds.
At the end of the day, there is no one-size-fits-all answer. Everyone has their own play style and preferences, and ultimately, it's about finding what works through trial and error.
The most foolish thing would be to look for a quick fix to solve all problems in one go. This applies not only to this game but to all aspects of life, I believe.
