The golds are pretty mild...

Up a notch are the black labels (not that easy to find)

The Italia's I would say were next

MX2's fall right about in the middle...

IMO - The Anniversary's are next in the power scale, followed closely by the Criollo's

The Brazilia's I believe are the strongest... To me, they taste a little bit "sour" - but I've come to really enjoy them.

My favs out of the line are probably the Italia's, the Anniversary's and the Criollo's... i have some 7 yr old black labels that are just incredible (a very nice creamy, nutty flavor to them - not overpowering, just really pleasant)

The nice thing about CAO's is I don't believe I've smoked a bad one. To me they're one of the more solid, uniform lines out there. CA rates most of their line 90+
