I finally finished a project that has taken a few years. I completed the last paddle in a series that is designed to see what fits any given person. Not just a guess,{as in anthropometric} but a try to see series. This series consists of 3 different widths of paddles> With 5 paddles for each width. The blade sections are all one inch different from the next, and all the paddles have adjustable looms. Infinite adjustments to try.
It's been a fun project.
