Preferences:
Size: Roughly 40mm, 50mm
Shape: I don’t like the squatty ones, no offense. Like the most I’ll go is width and height are equal, but not where the width is more than the height.
-Not really too boxy in shape… I’d like one that curves into the response, not one where the sides kinda just suddenly drop into the response.
-Rounded Rims, or Flat, No Sharp.
Weight:
Definitely not one that plays like a rock. I don’t care about weight, but about how it feels. Like not Genesis/DM weight… more of a floatier, moving weight.
Misc.
-A good grinding surface would be nice, but not needed.
-And I would really like spikes… cuz I always wanted a yoyo with spikes. 8)
From what i read on your preference, you might like a rounded undersize with spike.
i hardly think any undersize rounded yoyo with spike. But you might like the Hspin beysick or gorylla.
