Is this Yuuki Slack?:
I can’t really tell. I can’t see your string very well. But from what I can tell I don’t think you are doing it quite right. Just look at the tutorial here on this site and you should be able to get it. But I think you are pretty close.
You’re getting close, you just need to practice more to complete the trick. If you don’t really get it what you’re doing, then watch this video couple of times:
Happy Throwing! =]
Believe it or not, I’ve watched that video like twenty times before I tried the trick and then 10 more times afterwards. André said that you just swing from a double or nothing but other videos say keep the pinch. The cross in the string makes the slack better so I just need some more work on swinging.
Definetly and the pinch is best
