The FAST speed star. Literally the first yoyo I cared about
My yomega dash, first metal. Recently modded it to be unresponsive. Plays great. Never letting go of it.
Yyf ONE. My first “real” yoyo. I don’t count my plastic yomegas as real yoyos.
my yoyo jam synergy it sucks for string tricks but it is awsome for grinds 8) there is only prototypes for this throw.
I see what you did there haha!
For me it would have to be: You will never see these hit the BST ever!

Any Hitman. I just gained a love of throwing from that yo-yo that is just hard to explain.
My H5xChief- it’s so smooth and I love oversized!
Punchline repeater. Such a nice shape and a throw you feel like you can make art with.
For me, the answer is basically all the throws that I want to be a permanent part of my case.
That includes:
YYF Supernova and Genesis
Duncan Echo and Barracuda
And once I get them, these will be on that list:
YYF Shutter
Yomega Glide and Dietz’s new signature
Duncan Strix
For me it will have to be my YYJ Revolution, my first advanced yo-yo, I have gone through a lot with that one, however it is still in good shape. And it is what allowed me to realize that I like organic-shaped throws.
