I have not seen this suggested or maybe I missed it.
Give player the ability to purchase a Caddie Book for each course.
These books would contain detailed information for every green on the course. Detailed slope and elevation change.
This would enable players to try to figure out where is the best place to put their approach shot. Sometime being close, but on the wrong side of the hole is no good. Severe uphill/downhill/sidehill putt.
I would be willing to purchase a book, at a reasonable pric,e for each course.
I think this would be really helpful and there would be good demand for this product.
