I'am throwing on a Shimpo adjustable chair. I'am very satisfied with it.
Nonetheless, last Saturday when I was throwing a (too) big chunk to throw "off the hump" I got myself an inflamed tendon from elbow to the fingers and now I'am wearing (Doc's order) an arm brace for 2 weeks (night and day) to not get that "electric cow fence feeling" in my hand every time I move the fingers. No potting for me for 2-3 weeks. Take care of your backs folks but also take care of your hands and wrists.
