Well, the are each better than the other in certain conditions. The Rule (for me) is more of a heavy oil ball, and can has more backend. The Animal Untamed is great for the medium (for me) but has a tendency to back off on carrydown. I have 2 of each ball, one with its out of box cover, and 1 of each polished up with some Track Magic Shine. All drills are pin under ring, cg in the palm, with the mass bias ending either under the thumb or left of the thumb ( I am right handed, high track, 17-18 MPH, so higher speed as well). The Rule is better for the heavier oil or for some carrydown, where the AU would not get into a good roll or handle the carrydown, and the Animal Untamed is better for the medium condition where the Rule may burn too early and lose some of its pop.
The ball to choose would depend on a few factors: Amount of oil, carrydown?, and your specs as well (PAP, MPH etc)
I will be more than happy to try to help you, so write at any time. I am sure Rick and Ex will chime in as well with their opinions too!
THANKS!
