I have fished Tenkara with several rods. I like each one for different reasons, but I wanted to see how they stack up against each other. So I compiled an experiment similar to Tenkara Bum’s Common Cents Database or Teton Tenkara’s Rod Flex Index. My intent was to compile test results that were simple and not dependent on the rod length for accurate results.

First I placed the rods at a fixed height of 71.75” I only braced the rods at the handle – to allow full rod flex. The rods had their own natural flex which I measured (and rounded to the nearest 1/4 of an inch). Next I attached a 20 gram weight to the lilian. My intent was determine the action of the rods when compared against each other. The lower the “Flex Percentage” number the stiffer the rod is; conversely the higher the “Flex Percentage” number is the softer the rod is. The list is organized from stiffest to softest.
