Hi Sastark! And everyone!
I am torn between two lovers! The 1599 Geneva and KJV! Wife got me the Geneva for X-mas. I really like it. It seems just about the same as the King Jimmy in translation quality and the sources. I love how the NT face plate says "Translated out of Greek by Theodore Beza"! That is unbeatable!!
However, I teach Sunday School in Church. I use the KJV there. When I took my Geneva to show it off, nobody ever heard of it. Of course, the NIV is the pew bible.

If you use the KJV at church, it's almost a silent sign to us real Reformed folk of who we are. (Kind of like a secret Mason handshake

). My class is used to me using the KJV, and I don't want to confuse the poor souls anymore than they already are. I believe also that one translation should be used and read by one person in a classroom. (ME!!)
So there you have it. I hope this helps. I could go on, but I think I've hit the highlights. (I'm beginning to sound like a modern praise band though. I. I. I.)
