Christmas is coming, and I really wanted a new yoyo. I came across the YYJ theory, is it any good?
Or should I get somethin’ else?
If like it then yes. If not, then no.
In theory.
Seriously, it’s all about preferences. It’s good. I like it. That doesn’t mean anyone else may feel the same way.
I think it is good 
It’s decent but there’s other metal throws I’d consider over it in that price range:
Octave (Amazing throw)
Silly Goose
Sine//Saw
Minute
Eighty-Six 400 (my personal favorite)
Hour
Dibase 2
Shutter (Great Deal for performance)
G Funk
Nova
To me it was kind of a “meh” throw, it’s good at everything, but great at nothing.
Its on the faster side.
I love mine, suits my style.
Has the lateral caps, which means, FUN!!!
Good grinder.
Very stable and good for horizontal.
Its just a tad light/floaty/fast.
But thats MY preference so I love it!
O
Lol studio, I theory what you did there!
But seriously,Like sparhawk said, there are other yoyo that can outperform it in about the same price range.
My suggestions:
Shutter ( just ordered one and can’t wait!)
Magic yoyo t5 and n12
Werrd time series (heard good stuff about it )
Also I suggest getting it before November 8/9th so you can take advantage of that sweet free shipping( on orders over $20).
