Weird string concept

While yoyo mods are huge, I have really yet to see anybody mod a string. So I love slacks and whips,but the trick for these is having proper string tension. I was wondering what would happen if you could invent something to keep tension constantly neutral. I was wondering if by your finger knot you could implement a swivel of sorts. That way the string instead of twisting the string the swivel would just spin . Tell me what you guys think or if anybody has tried any other string mods.

Thanks croc. I knew it was too good of an idea for somebody to not have tried it before

No problem :). And I’ve never tried it but I’ve hears it’s pretty cool.
