I shot the skaters with a Phantom MIRO LC320S made by Vision Research: http://www.visionresearch.com/Products/High-Speed-Cameras/Phantom-Miro-M320S/ Most speeds were around 3271 fps, but I shot the full body shot at 1200 fps.

The stick rigidity data collected by Dr. Evans and I is not a formal reflection on the manufacturers because the sticks were previously used and we could not find an ASTM standard to setup our test. The possibility exists that I put the support positions too close together, which would make the values lower. The players however gave us the sticks because they were "so used they were now flimsy". Our data reflected this. If I had it to do over again I would test a new stick vs an old stick. Kettering University has done some research on this subject and we tried to setup our test apparatus similar to theirs. They applied the force to the foot of the stick. We applied the force to the center. http://www.kettering.edu/news/taking-stick-check

I thought this was a great video of a product that has normalized the process by constraining the 1 inch deflection measurement.
