Thats a cool looking core shape!

Sorry Lillian, Seismic doesn't copy other core designs like other companies do. From what I've been told, it's along lines of the Isignia core line with some tweeks. I haven't received any other info except for that video above.

I can't wait for this ball...hopefully it is release on my birthday in December...definitely saving the ducks for it...I love my current arsenal of Seismic pieces and believe this ball will only add to the fun I'm already having now....

Usually it is what appears to a person's eye...we all know that the cores are pretty dynamic and have their differences on the R&D level that we can't see...
Hell, when I first saw the Heritage, I instantly thought of the Lane #1 Stealth Bomber core: http://www.lane1bowling.com/products/balls/stealth-bomber/index.html

I'm with Doom on this one. Cut off some of the protrusions, making it a bit more blocky. Looks like it's going to be something a little earlier, and pack a huge punch. Now I'm thinking of holding off on getting into Seismic until this one launches... Or to get a Stampede and this... Decisions are not easy!
