Considering the fact that "Loose Balls Rule" what about custom made titanium balls, cups, and spindle. Sure... Why not... If ya got the bucks...
Sometimes when I take a really good dump I wonder how much weight I am trimming off my next ride... sorry not to be rude.

Looks like you got the problem solved and by the way... NICE BIKE!!!!!
