OK I think everyone has this problem.
I can normally tell after a couple practice shots if this ball will work on this shot.
I did have one moment a couple yrs back when i first bought a La Nina, i was so intent on making this ball work, and i used it for about a month, and in doing so i dropped my avg from 200+ at the time to low 180's lol.
But since then, i have been able to tell if a ball will work or not. and can normally tell once i am warmed up, i normally only need 5 shots max.
