The advice given is on the mark - but, man - congratulations! Getting a bow to shoot is a huge accomplishment. I think I got my first shooter this past march and it was #6, or 7, too.
I learned a boat-load from good hickory boards. Hickory is forgiving and functional. That is my recommendation.
Congratulations, again - seeing the post "my first bow" is my favorite to see on this site.
Much appreciated.
