FUnny how everyone seems to be saying the Delta 1 is so much stronger than the original RUle, while Track themselves list the hook for the Delta 1 as 39/29 and for the RUle as 40/30, with the number's representing overall hook for Dull/Polished balls.

Funny how that works out, isn't it?

Rule Delta 1 vs. Original Rule

Can't deny that I love both of these balls. Here is my comparison of the two:

Rule Delta 1 Layout:
4 1/2" Pin above with a weight hole and Mass Bias at 5 o'clock.

Rule Layout:
3 3/8" Pin above, Stacked Leverage with a weight hole and Mass Bias at 5 o'clock.

Reaction Shape:
The original Rule has a smooth arc reaction to the pocket while the Delta 1 has more pop on the back end. The Delta 1 reads in the mid-lane about 3-4 seconds quicker than the original Rule. The Goo-LS coverstock also compliments the core in the Delta 1 and I believe despite the ugly colors (LOL) the Rule Delta 1 hooks slightly more than the original Rule. Hope this helps!
