The Zr40 to begin with is just simply a great looking ball, great color combination, shades of charcoal grey pearlized cover stock polished to gem status, high lighted with bright yellow logos.
I chose to use my favorite drill pattern, 4-1/2 x 3-1/2 to compare it to its predecessor the AU 79. The Au for me was very snappy and on occasion was almost too violent at the breakpoint; the Zr40 is much smother at the breakpoint. It is still angular, but not the skid snap I had seen in the AU. Even feeding it into the drier area too soon it seemed to bounce without over reacting as the Au would respond.
Lowering the rg differential has tamed the backend somewhat but in a more favorable way, it is smoother, more controllable without sacrificing the backend or loss of hitting power. I only had to move my feet a couple boards right to play the same line as with the AU, but with one noticeable difference, I did not have to adjust the balls path as much or as frequently as with the AU, lowering the rg differential seemed to have made another positive improvement for my game, less adjustments as the shot begins to transition. It handled moderate carry down without any noticeable difference; this benefit has to be attributed to the Soaker’s footprint, excellent read, sustained hook without over reacting when encountering the drier area of the lane. I have approximately 21 games on it at the time of this review, and it has become my favorite ball. As usual another top tier ball from the “Guys†at Dynothane headquarters.
In a nut shell the Zr40 can be considered controlled violence.
