It is absolutely vital that you can do a PROPER bind if you are using an unresponsive yo-yo (which is what you need for new-school tricks). If you don’t do the bind right the yo-yo won’t wind as well, leading to reduced spin time, and you will dramatically increase the chance of getting a tangle when you throw. Tangles lead to yo-yos colliding with your head very hard when you make your next throw. It hurts. Bad. Learn to do the bind right.
Standard: On a regular throwdown you do a reverse bottom-mount, pinch the string with your free hand, and then pull up with your dominant hand. Follow these instructions exactly and you will get a nice wind that won’t tangle.
Side-style (Poyzer Bind): On a trapeze throw you unmount the trapeze, bring the string into the gap, pinch the string with your free hand, and then pull up with your dominant hand. You can also get into the mount by doing a reverse trapeze. It’s all the same in the end, because really both types are the same thing, it’s just that you get into them a little differently.
