NXT Tour-S should be a good  starting point   If playing competitions, it would be time to try the Pro-V products.

I agree with Don. It's just a matter of preference and available funds, but a ball that performs consistently - especially in close proximity to the green - will make a significant difference in his ability to drop those scores.

I am no professional and this is just my honest opinion and I am sure a Titleist staffer will give some solid advice  on which ball to use.I would start with the DT solo a amazing ball at a great price. that won't break the bank for a youngster learning the  game.

If you truly want to know what is the best ball  to play,take him to a golf ball fitting day.

Good luck.

Couldn't agree more!
