String tension

Ok so I just got into yoyo about 2mouths ago and I’ve foot summ pretty good tricks but I could never figure out how to get a perfect string tension plz help!

My favorite way is first get in a trapeze then (if you are a righty) bring the string that is the furthest to your left into your throwhand. Then take the string that loops aroung the bearing and move it perpendicular to the yoyo out in front of it…it will then spin around the yoyo loosening the string.
