If you are looking down the length of the string with your spinning device at the point closest to you, it should spin clockwise first. Then fold and spin counter clockwise.
Yes there is. “left handed string” is twisted opposite to right handed string, meaning that the string will get tighter when thrown, rather than looser.
And augmented, just twist the string the opposite way you are right now.
99% of all string is right handed, as most people are right handed. Left handed players have learned to deal with loose strings, rather than tight strings just because right handed string is so much more common.
