Here are the weights for ours, our scale only measures to the nearest 5g:

Original in KOP: 295g

New FIRST boulders (grey) recieved yesterday:
285g
285g
300g

Of much greater concern to our team is the remarkable increase in stiffness of all of the new balls. Our shooter compresses the ball, so the new stiffer balls slow the motors more and travel significantly less distance. We set up a jig to measure the force required to compress each ball to 8 inches. Results...

Original KOP Ball:
6,300g

New Balls:
11,860g
11,235g
12,890g

We don't know how much of this is due to the older ball being broken in, but we don't believe that it ever flew that poorly even when new. So is it an issue with differences in the foam from batch to batch or was the first ball just an outlier?

We will post a picture of how we measured the compression. If you can obtain data for your own boulders to compare, please post them as well.
