I used to be able to get JB to outspin MB, but only when near mint. Then they made JSB, and I love it, though its stamina performance is still just a little short of what I would want from it in Limited, it's still a very usable tip for various things.
Also asking again, because I'm pretty sure I'm on the right track after further developments - if anyone has a Hasbro or Brown Takara F230 they don't mind rendering permanently illegal in the name of SCIENCE!!! and like $15 or thereabouts for the other thing needed (should be available at any decently sized hardware/trades store, maybe also RC./Electronics Hobby stores if they stock parts and tools etc, may actually have some legal use for beyblade stuff too, looking into that right now actually) shoot me a PM. Obviously it also has to stay between us (and any Committee member who wants to know what's up) at least until complete.
