@Charlie Chong Thanks. It took me a lot of practice to get the “basic” 540. I had already got a pretty good spin hook 30 years ago. Then, I practiced jump hook, 360 side, 360 hook and a lot of step by step for 540 spin hook. I still think I have to master the 360, kick higher and turn faster before I can get a decent 540. Thanks for your encouragement and those tutorial videos you made.
