From what I've learned on Free Republic, if it was there in 1616 then that is all that matters.
I will mention why I prefer the King James Version. The KJV is really the Tyndale translation. Tyndale was burned at the stake for his trouble. The KJV scholars used Tyndale as the basis for their edition. Tyndale was within Luther's circle, another plus. The KJV was good enough that it was virtually the only English Bible until 1950. The KJV was supposed to be read out loud, so it reads well in public use and is easy to memorize. Modern versions are great if someone has a tin ear for the English language. The modern ones (even modern versions of the KJV) insert their doctrinal preferences into the word choices.
