I just shot lots of video with another great youtuber, Dustin from Huntsville/USA.
He runs an excellent youtube channel called "Get smarter every day". Here:

I picked up Destin in Karlsruhe and we drove to Tobias's farm, just 30 minutes away. The sky was still overcast, not great for the high speed camera... but it was bound to clear up later on.
We set the equipment up - wow, what a camera! A "Phantom", made by the US company Vision Research.
A 1000 frames per second at 1280x720 resolution (HD)! I don't really know how much this beauty costs - but I am sure it is worth every penny.

It cleared up right on time, and we did many great shots... smashing particle boards... smashing pumpkins... smashing three pumpkins in a row with the big cannon...

We also did the test that was suggested here, with "striped" bands. I cut three bands, one untapered, one with a decent 2:3 tapering, and one with a very aggressive 1:5 tapering. Tobias did the shots in full butterfly, the footage is frontal.
I will now be able to draw up an accel curve of the ball in the pouch. This can hopefully shed some light into the dynamics of tapered bands.
