Thanks for sharing your experience, I think it will help encourage folks who haven’t yet to give it a try. You have good review points but I read this more as a spinner’s log, star date 1. Keep coming back and share your status.
Spin top string is different from yo yo string in several ways; thicker, 3-ply instead of 2-ply, usually cotton no blends, no loop at one end, lasts much longer than yo-yo string, you can even wash it with your clothes (just don’t get it near any fabric softener).
You might pick up a fixed tip also, bearing tips are great but to get the full experience you should have both. The Short Circuit is fantastic.
