Bearing: 10-Ball
Response: K-Pad
String: Neon yellow YYE Poly
Full sized, around 56mm, anywhere from 39-43 mm wide, gap in the 4+mm region, and V-type shapes. I won’t lie, the Phenom is a favorite, as well as other V-shapes. I also like the KK bearings but I do play lots of other stuff.
Shape: V shape
Weight: 65-67 grams
Size: doesn’t matter, as long as it’s not oversized
Response: Silicone
Bearing: konkave
String: YYE bulk
Shape: Doesnt matter too much to me.
Weight: As long as it plays a little bit on the slow side, I’m happy.
Diameter: 50-53
Style: Slow and smooth
Response: Silicone
Bearing: Whatever came in the yoyo (I’ll occasionally throw in a Center Trac)
String: YYE Bulk
I prefer a V shape. I like having my hand as close to the bearing as possible when I throw it.
Whatever a royale is. Haha
A yoyo… that is just about it.
plus string! I gotta have string. I mean without string it’s just a cookie cutter 
. mmmm Cookies!
If you get one of those ultra wide yoyos, you could use it to roll out the cookie dough and then cut it.

Genius! Pure Genius! 
I like these threads.
As for me, it’s gotta be 66 gram, no more, no less. 56mm dia, 43 width. And a slightly organic How shape, like the Avalanche or Code 2. Perfection.
V shape, 62-65 grams, around 60-64 mm dia, and 43-47 mm width.
