Likes:
Gets through the lane with ease with strong and  controllable backend continuation.
Dislikes: Without sanding:
Throw it in heavy oil, and it will skid 40ft.
but this one definitely better with some dry boards to grab
But for anything other than heavy oil, it's a keeper

Dyno-Thane - Element ZR40
Compare it to its predecessor the AU 79.
The Element ZR40 is much smoother at the breakpoint. But still angular,
Even on drier Condition it seemed to recover without reacting early
It’s smooth and controllable without sacrificing the backend
No loss of hitting power.
I only had to move my feet a couple boards right to play the same line as with the AU79 but with one noticeable difference,
I did not have to adjust as frequently as with the AU79
On a variety of shots,
Element ZR40 worked best on medium to light oil
I was able to throw this ball on heavy oil but it’s Factory finish is a little too shiny
This ball is best suited for a medium-oil, carry-down house patterns
I recommend sanding it with a green pad and you wont be disappointed.
This Increase will surprise you
You'll have to move your feet left.
The ball really impressed me with the ease of length and the hitting power.
The ball actually as good if not better than the AU 79
