WandsI won't put anything here, but only suggest that you go to Pottermore, and if you are a member there, you should look up all the wand woods and cores and flexibility (favourite them, I would suggest). Reason being, there is an amazing amount of info on the woods.
I'm not copying and pasting here simply because I don't know whether that will be breach of copyright or whatever.
Another site, pointed out to me by
Andy, is
Wizard wands, which also has some info for those not on Pottermore.
