Similar question to the best clubs for 6-8 yrs old but looking for the most optimal ball.

Curious on your thoughts.

Average driver head speed from radar is 60mph and max is 68, just turned 7.

Initial thought was low compression and high spin to keep the ball in the air longer. Looked at USKids 45 compression. They say for speeds up to 70 ball speed. They have a ~ 60 compression for up to 90 ball speed.

Curious if the 45 compressions go further than if I use prov1 since this speed can't compress the bottom core on the v1 to get the spin maybe?

Curious what longest, highest spin balls are out there for this situation.

thanks
