Hi Cedriver, with all clubs and ball combinations, you really need to map the clubs with the balls.
Another point you need to be a ware of, is with the top level Nike balls, full backspin tends to lead to greater variation especially if you miss the ding.
But looking at your stats a 55% GIR suggests you will be better off mapping one ball, learning what the effect of spin makes, and sticking with that ball.
In your case I do not think it is the ball, but the execution. I would be happy to have a hit with you, hopefully see what is going wrong.
