I'm a huge fan of their tobaccos, and since Bayou Morning is one of the blends you mentioned, I smoke that pretty much constantly and can't recommend it enough. I actually really like the "rough edges" or harshness in some of their blends, because like the OP, I really like strong potent flavors. I have never noticed a difference in the bulk v/s the tins, and I love the value of the bulk! And just to add to the list of great blends that everyone has mentioned, you should check out Big 'n' Burley, and a definite +1 to Bayou Night, which MSO mentioned.
