Morphy, I really don't care if you share it. It's on a public website after all.
https://youtu.be/AZGlEKCkjicNot as accurate as you, Jaegoor, but this was after about 30 minutes of practice and I wasn't concerned with being accurate.(I have practiced a few times previously, months ago, too). As you can see, I'm pretty clumsy getting a new ball reloaded. This serves your point about the extra spin giving you more time to grab another ball, resulting in more fluid motion overall. However, If I can get setup so I can grab two at once, I think I can get 12-14 shots in 30s if I can cleanly grab 2 at a time from my bag. And Fluidity will likely come from a bit more practice.
But I think that you are right, Tint demonstrated the fastest speed slinging I've seen. I think the video was taken down. I found his other videos and didn't see his fast slinging video.
Yes, I took it down. I was worried protesters in Hong Kong was going to use slings in their resistance...It's back up now.
