I remember the three things being thrown out as the possibilities as 
well, but in GoF isn't Fleur Delacour's wand core her (grandmother's) 
veela hair?  So it was obviously a wand made specifically for her, 
but that might mean there are many possibilities.  

My question is wondering whether the wand core, of a wand chosen 
specifically for the witch/wizard, shows any kind of compatibility 
with other wizards... man, that's just not clear.  What I mean is, 
would someone with a dragon heartstring (like Krum) be better suited 
to someone else with a dragon heartstring (like the presupposed 
Hermione)?  Or would it be like in magnets, and repel?  Just a wild 
hair...

Adan, not knowing where I'm going with that last bit which isn't all 
that unusual, really...
