Wow! Thanks for the answers, guys!
Bloodwood is a very pleasure surprise for me.
I know it with the name "Muirapiranga" here, and I didn't know that is a bow wood.
I certainly will try use it!
Jatoba I tried some times, but as the fact it is the same value of ipe, and ipe is more easy to find, in most cases I prefer to buy an ipe stave or deck... (I think it better too).
There are many variations of Ipe here MoeM (Roxo, Cumaru, Champagne, Amarelo, and goes on) I don't know exactly what kind you can get, but some of then is really not so good.
Roosewood is realy a problem... rsrs.. It's dificult to find and very expansive. Hard to believe, but I could tell it more easy to me buy outside Brazil, pay the taxes, and the price will be less than I buy here.
Thanks guys!
Cheers!
