Hi Earlyrolling - Not sure about the goal of your question. Every ball manufactured has engineering designed into the ball for a specific performance window. Elements of the engineering are
Asymmetrical (Badger) vs Symmetrical (IQ Tour) Cores, RG, Differential, and Intermediate Differential. The cover stock can be Solid, HyBrid, or Pearl. The cover stock could include Mica for traction. Not your two balls. Coverstock grit level can range from less than 500 to over 5000. Your two balls are 4000 Out of the Box. In the case of your two balls one is Asymmetrical and the other is symmetrical, IQ Tour Solid. The users Stroker, Tweener, Cranker, all like the IQ, high grade at 9.5/10, over the Badger high grade 8.5/10. Don't forget the power of the Dual Angle Drill pattern. Gold Coach Denny
