What is the best golf ball for an amateur? Distance?,Etc

Marty’s Answer - Just like clubs many manufacturers produce balls and each have multiple lines of balls to choose from.  

By far and away the Titleist Pro V has led the industry is sales for years.  It is the most popular ball with amateurs and professionals alike.  It is also one of the most expensive balls on the market.  

I always recommend finding a ball that a player likes that balances value and performance.
Consider distance, spin or stopping power, feel and price.  And then STICK WITH THE SAME BALL!  The way a ball consistently reacts especially on short shots around the green has a huge influence on score.

The best most cost effective way to try lots of varieties of balls is to find a course with a used ball bin and buy lots of different types (at least 2 or 3 of each brand and type) and find one you like without the expense of buying new.
