A statement or two and then a few questions.
The 720 looping yo-yos we’re designed and tested by several of the best 2A players on the 3rd planet from the Sun. My personal opinion is that all yo-yos are a work in progress. No matter how much research and design engineering goes into a yo-yo call it eventually it’s probably released. And then within a few months up to maybe a year after release, after more players around the world offer feedback on the yo-yos, the yo-yos may get slightly tweaked in future releases.
The 720 is the signature yo-yo of one of the best players to ever throw 2A. Shu Takada could probably do a decent to a routine with coffee cups tied to shoelaces. Shu uses the 720’s because they are amazingly efficient loopers.
Now…… that being said, why would you switch over the 1 720 to Sunshine spacers and a different bearing and then ask questions about the function and performance of the yo-yos?
If you are just starting 2A, you should lube the bearings and just throw them stock until you get a better handle on actually learning to loop.
Switching parts out and throwing looping yo-yos dry…… and with the wrong string is not a good recipe for success.
When beginning 2A, loopers that sleep are not a priority. The priority is to get those yo-yos in the air and start practicing your timing.

Somebody may tell you a story about how they got a butter knife and carved their own looping yo-yos Out an old wooden rocking chair. And how they made their string from the shoelaces of old army boots. And how they locked themselves in a cave and practiced for 10 hours a day by candlelight. And now they’re really good.
Fortunately in the yo-yo world of today, the equipment is already there. Designed for faster progress. Looping yoyos, custom-made yo-yo string, thin and thick lube as needed, and countless videos that show you how to get rockin from beginning to advanced.
Anybody that gets into throwing yo-yos is by nature going to try experiments and investigate little things on their own. One of the keys do not heading in the right direction is to not personally try to over engineer something that’s already there ready to go. You just gotta put some strings on your fingers and get those lubed yoyos in the air.
Probably the best length strings to start with are approximately 29 to 30 inches complete finished length. That means from the loop end of the string to the actual end of the tied loop. So you start with a string that’s about 36 inches long. Get a ruler and measure from the tiny knot on the end of the unfinished string 4 inches from that point. Get a sharpie and put a dot at that 4 inch measurement. Bring the knotted end over until it touches the dot. Make a fixed loop. That will bring the 36 down to 32. At that point when you fish the string through the loop that you tied that will account for another 2 inches. So, now you’re at 30 inches. Depending on how accurate you do things, you may end up at 29(no big deal).
Very advanced 2A players can use longer string because they have their timing down very well. But when you’re just starting out a shorter string is usually better to help Dial in your timing.
You don’t wanna go too short starting out, because once you get under about 27 inches, you really have to move fast and it creates kind of a mechanical feeling. Just an extra couple inches you’re missing reduces the ability to have a more natural flow and mentally adjust your timing in a more relaxed manner. I’ve seen people using strings about 22 inches long and it looks pretty crazy.
Shu uses and suggests 75cm which equals about 29.3 inches. He spent years dialing in the ideal length for his world beating performances. It’s really nice how he saved a lot of us a whole lot of wasted time trying to figure out a pretty accurate length for effective looping.
Good luck
