Probably Spin Dynamics… I love undersized throws, they make fantastic ones… And they are in the process of getting a new one into the market…
C3 or YYJ
Ten Yoyo
General Yo
CLYW
Grand Rapids Yoyo String
Clyw
No one, because I suck and wouldn’t want to bring a yoyo company down.
right now i’m digging bigyoyostring and twistedstringz… both have amazing durability and feel… sooo either of them wuld be sick to get for free lol 
;D
I would go with either CLYW or OD, SPYY has a cool team too.
I prefer either Yomega or Yoyojam, because they have wide range of choices from beginner to advanced. Also they are two best company if we’re talking about 2A.
Judging by how awesome of a guy big yoyo is… big yoyo string!!! (Hinty hint hint )
Or one drop. I would gladly be held to using one drops in compies and stuff
lol dude ur probably not that bad :). Plus, we’re assuming (since ur being sponsored) that u r really good.
CLYW
Lots of CLYW :). I don’t blame you guys. Caribou Lodge is the bomb… Soo sick
I like their yoyos, but I don’t think I love their yoyos. I do love spyy’s yoyos
sorry, I’ve never SEEN a spyy yoyo 
I Immediately change my answer, CRUCiAL.
Kitty String
you’re missing out. 
I highly recommend getting one as your next yoyo.
