NOT AN EXPERT,

 But I did catch the same thing several years ago when this was happening. Several different people had different info they were spreading about the ball, and I emailed Ebonite about it.

 Was told that the confusion was caused by having tested several cores with that cover, deciding to go with one, then changing their minds “at the last minute”, which caused some incorrect PR material to get out.

 I was told the VERVE core was supposed to be the correct core for that ball during production. Couldn’t find the old email I had about it, but I am absolutely sure that’s what I was told back then.

I remember this topic! Lol good ol' EBI

Juggernaut,

Thanks, I like the looks of that core in the Warning Sign and the Exceed.

Of course I have nothing against the Vital Sign Core as I have Fantastic ball(2 actually I picked up a NIB backup) of the incredible unsung Ebonite Signal.  Thank you EBO!  What a hidden Gem!

Just wanted the more midlany Verve core to try an idea!

Thanks again Juggernaut!

Sincerely,

Luckylefty
PS what i amazing is that one of their videos right from EBO(as above) and I believe even bowling this month showed the Vital Sign core in this Warning Sign what a cluster!
