Noooo nooooo long string. Don’t do it. Thinking you need long string because of your height makes no sense. The yoyo doesn’t know how tall you are, it’s not going to play differently just because you’re taller, and it’s certainly not going to be easier for you. I guess i understand wanting long string if you’re learning some tech trick and need the extra, but for every other application i’d argue a shorter string is faster, easier to control, easier for whips and lacerations, and looks better.
Look how short this string is:
Not saying you need to go that short, and i’m sure your playstyle is different anyway, but for people who have only tried pre-tied string you should shorten it up and see how it feels. Nothing’s worse than watching a new player with long string have to flail their arms and entire body around trying to maneuver it into the positions they want, just looks really awkward imo.
