Apart from "special" courses, it's difficult enough to find a ball in any rough after a 180 yds shot. Pros have their patrons to help!
Alas, I stopped thinking of individual balls, lost or worn to zip. To me, it's but an entry fee, so many credits for a game. As a rough figure, I use 1/10 of a sleeve's price for a 9 hole round. With Tour-SDs, my long time friends, it was 6 crs per round, with my current favourites, lvl33 Callies, it's 25. I also see it as an investment to gain fun and recreation, and from this viewpoint, it comes out as a very affordable pastime.
Those who want more, pay more, those who play it the budget way, pay less.
Instead of crying and shouting when a ball is "lost", you might think of the collection box passing - time for a donation for the game!
