Ok so I have never cut my strings in all the time that I have yoyoed and I am starting to wonder is there a benefit to having a shorter string does it make sideways yo-yoing easier? Does it make play easier or harder? as I can imagine that longer string would usually mean larger gaps but does also having you hands farther apart give you less control? I have always heard the cut at the belly button but always wondered why. 
Thanks for taking the time to read this post.

This is all dependent in your particular style of play. If you do a lot of tech, slacks, whips, and scuicides, then full length string would be great. If your a speedy player, that does speed combo’s, horizontal, and rejections, than a shorter string would fit you. try to experiment with different strings, and different length’s. This is subjective to your own self benefit’s, and personal preference. I personally use full length string, but I differentiate length’s with different yoyo’s. As a result, the old saying to cut the string at waist height, was all made in the past with older yoyo’s. Hope this help’s. ;D
I completely agree with grandmaster. Does a shorter string make horizontal easier? If you’re into technical stuff than I’d say yes. It allows the yoyo to travel a shorter distance increasing speed. It’s really all personal preference.
Cut my string a played with it for a while and is seemed that some of the slack tricks were easier. but I can see how with stuff like jade whip and iron whip the longer string would be better and make the trick look better a well. But I also see that longer strings give you the ability to make crazier string structures so I see how both can be good, and I will definitely will be playing around with string length to find out what is best.
Thanks for your feedback!

What’s the best way to tie the knot? That’s always how i end up with random string lengths
That is incredibly hard to explain with text! XD

This is how apparently everyone else ties it but I do it differently.
jhb8426 how did you embed the video? Did you just put the embed code or what?
Just remove the s from https in the link and it should do it automatically.
cool!
