I’ve been yoyoing for close to 5 years. I’ve found the perfect yoyo several times throughout my experience. I made a really ridiculous, long post on another board outlining just about all of them. Maybe the first time I found a yoyo that I felt really suited me was when I got a Legacy at US Nationals in 2008, which I think was before they actually came out. By that time, I had been yoyoing for like 8 months or so.
I have a lot of perfect yoyos. I expect I’ll continue to find them, but I also expect that even though I keep finding them, I’ll keep looking.
