My suggestion would be to pick one of the two, either one, and stick with that ball for a while. As your game progresses you will find the subtle differences between any brand/style of ball can affect your shots, especially putts. If you want to be as consistent as possible, minimize your variables. Good luck and have fun out there.

Ditto what Dale said.

Using one ball for everything gives you a feel for all your shots over time. I would suggest you also get some spares to use in a practice bag.

Over a few weeks to a month you'll know how many hops the ball takes before spin sets in on a wedge shot, what kind of roll out for a flop shot. Eventually, if you take notice, you'll know exactly how the ball your playing will react on every shot

Have fun
