This ball is a pearl reactive.  From what I can remember, it clears the heads pretty well and makes a nice, smooth continuous arc to the pocket.  I had one right after it was released and it was my favorite ball just because it was a pearl that was pretty controllable on the backend.  This ball will fit in the light to medium conditions.  Give you an idea.  I have a 540 rpm rev rate.  My ball speed is around 18mph.  On a fresh house condition (standard crown 10 to 10, 32 feet buff to 38, I played between 12-15 at the arrows fading out to about 8-10 and it made a really smooth move off the dry and hit was pretty good.  It is very comparable to the Messenger Ti Pearls, but a touch less on the backend.  A good ball if you want a ball to clear the heads well without the jerk off the dry.

It is reactive, damn I loved that ball I sure miss mine.  Mine cracked because I dropped it one a small peaice of metal from a broken toy car and it stuck in the ball and cracked it.  That so f'in sucked.  Anyway it is reactive, same cover that was on the Vortex 1.

I can hear the voice
But I don't want to listen
Strap me down and tell me
I'll be alright
I can feel the subliminal need
To be one with the voice
And make everything alright
