>>6047457The WBO is a pretty well established community, and they have a wiki that is pretty fleshed out. News mostly comes from the news section of the WBO and if you're talking about reference guides on parts and how to play, the Beychannel has videos on launch techniques and the wiki has a huge reference of parts and their functions, not to mention the WBO threads that cover part selection for top tier combos.
>>6046984There are finely machined blades out there, Beylon in particular is a user who is currently trying to get his own high-end fighting tops on the market, and Lowen93 was making laser-cut full metal attack rings and sub parts, as well as another user who was making 3D printed custom designs and revisions of old attack rings to fit MFB setups. I don't know about ruby bearings ever being used, but plenty of people would tune their bearings, which has since been made illegal for official play.
