Thank you for reading my post.

This was a one time run of the original SD73 Pearl.  The differences are the color of the ball and there is no mica in this coverstock.  This will get the ball down the lane a little better with a little more pop on the backend.

Remember now, just because the ball flares 10" doesn't mean it will go sideways.  This ball by no means out hooks a SS pearl on the backend.  When you start getting into 60 or 70+ differential that saying that the more the differential the more the balls hooks on the backend doesn't apply anymore.  A ball like this flares almost all the way around the ball.  So what happens is the ball is flaring, flaring, flaring, etc...and normally it would then come off the oil, find the breakpoint and makes its move.  Well it keeps going and what actually happens is the ball flares so much it slowly starts to back off a bit.  Great ball though, just don't think you are going to buy this 9+ flare bowling ball and it will go crazy on the backend.  This ball is defintely not meant for that.  The backend reaction fits right in between the SS Pearl and Pure Fuel.  

If you have any other questions on this ball please email my work address at RogerN@rotogrip.com.
