I think more bearings setups would be pretty awesome. Though I will admit it’s nice when everything is the same size as keeping spares is much less complicated.
Interesting. I wonder what other weird combos there are. I’m cool with C, D and half spec but I work with equipment that has proprietary this and just-a-little-bit-different that and it’s infuriating. You’re not special, you’re RJ45 going into steel conduit. Your connector doesn’t have to be special, you’re gonna get routed into a switch anyways. That being said, them little Bangarang bearings, I wonder what that would do with a full sized throw…
If it makes a clear difference in a yo-yo’s performance or capabilities, I think it is justified.
If the difference is subtle, I think the downsides related to limited bearing options, hard to find replacements and incompatible spare parts take over.
I’d guess that would be a more difficult to find an interesting candidate bearing for an unresponsive yoyo than something to use in a responsive yoyo. Trying different bearing sizes seems more likely to have benefits for responsive play. For unresponsive, it seems like it would be difficult to un-seat (no pun intended) the C and D as the ones to use. Especially since non-flat seems to be peoples’ overwhelming preference.
