I can understand why sticking with KJV is a good plan, there are so many questionable translations out there, with (I believe) agendas behind them. That's why our family switched from a paraphrase bible to the trusty old King Jameth.
My favorite books to study are Romans and Galatians, because in them Paul talks about contrasting laws - the Law of God that Paul calls "holy righteous and good" and "another law" the law of sin (and death) that Paul says is "bondage" and "worketh wrath" and "cannot please God". This took years to decipher and it's difficult given the very well established systematic theology taught within religion and culture.
