If you havent been able to see what this is all about.
you are missing out
awesome technology to use to see what you will get in a new ball
http://blueprintbowling.com/Ask your pro-shop if they have it.
Little pricey yet for the bowler.
designed for pro-shops.
soon, you will be able to get your own blueprint numbers without needing a pro-shop to be able to give your driller to enter into this program.
Your pro-shop can figure out your numbers now on his own now, but it is a little time consuming.
Simply enter your specs, lane conditions, drilling, surface, etc
It will show you the ball motion on the lane in the software.
want to add a weight hole?
it will show you the new motion
I wont buy another ball again without using this
no more guessing on what you will see with your new ball
