i get great spin with this sling.......paper balls and regulation baseballs.
during the few moments when my techniqe is good, it nails the target hard.
these are a couple of pics of my first sling. its a modified version of Zorro's medical tape design. made of 2.25 inch medical tape of course some tread and two pieces of nylon rope(# 15 i think????) with a total of about 72 inches (183cm). it has a tripple split design. i'm not sure how much longer it will last. as soon as i get my other slings made i will retire it
i'm in the process of the last steps of my second sling and in the planning of my third. i've been thinking about the hand woven split-pouch design
