Hey Billdozer,
Sorry for just replying back to you. The reason why I say first time in bowling history is because of the fact that when other companies tried to make both asymmetric and symmetric cores, shapes were the same, but true core numbers were different. For instance, let's look at the Pursuit and Pursuit-S. Pursuit was a very low mass bias core with numbers of 2.49 RG, .054 Diff & .008 Int Diff. The Pursuit-S had the symmetric version with numbers of 2.51 RG, .056 Diff & 0.000 Int Diff. Now the numbers are close, but not the same. Also the asymmetry of the Pursuit is truly not high enough to make a big difference. As per most designers, it takes a .010 or higher int diff undrilled core to really make mass bias play a huge role in terms of ball reaction. Also the Pursuit and Pursuit-s had pretty close to the same core shape, but they did change the shape to create the asymmetry. So looking at the Inception and Truth, you have the same core shape, same core numbers, the only change is .024 Int Diff which is pretty big asymmetry in the Inception and in the Truth, Int. Diff is .000. I also want to bring up the I-Core from Track as well. So if you look at the Paradox and Track Tour Sic, the core shape is no doubt the same. The big difference of core is when changing densities to go from an asymmetric core in the Paradox to the Tour Sic, you see a big difference in core numbers, which definitely isn't a bad thing. I just believe that what 900 Global has created is truly a game changer. If you ever get a chance to talk to Pros, they will be honest and tell you there are some days where a symmetric core goes through the pins better for carry, and there are some days where asymmetrical cores go through the pins better. I think both balls no doubt have a place in the bag for tournament players. I also believe that for some average league bowlers, it will depend on rev rate for which ball you really want if you can't have both. Lower rev players should like the quicker change of direction with the asymmetric core in the Inception, higher rev players will enjoy the blended reaction from the symmetric core in the Truth. I hope I could not only clear some things up, but even try to help put it in simpler terms. If you have any other questions feel free to ask. I will try to explain the best way I can.
