With only the info you supplied I would think that the Rule GP2 would be a better fit. The Animal is a very "arcy" ball, the GP2 has more backend movement.

Hey leftyk,

How heavy a condition do you encounter or want to use this ball on?  The Animal can be a little snappy if shined up and drilled that way but then the condition that it would be effective on is more of a med to med lite oil.

On a heavier oil condition, I'd definitely go with Excaliber's suggestion of a GP2.  Currently, this is the strongest hooking ball on the market for heavy oil.

Make sure there is oil. And i do strss oil I try to play 20-25ish to 9-10 and my gp2 is still burning out on me. I went from max leverage to very tame. Pin is in the center above bridge,cg under the ring finger, mb drilled right on the thumb. The ball is def an oil eating monster but might think its not cause its burning out on you on what you think is heavy oil. That brings up a good question. What is considered heavy oil. People around here think a norm fresh house shoot is oil. Where i consider it med.
