Mine obviously uses the KJV like most IFB churches. However at the Calvinist church where I fellowship with the men they primarily use the NASB for preaching, however when the men get tougher the leader uses the 1984 NIV. It appears the church allows leaders to use whatever translation they prefer as long as its orthodox. I like this philosophy, which allows freedom in the church. Not a common one among IFB churches I will add.
