I also read the KJV on top of the OSB. There is another Orthodox Bible version called the Classic Orthodox Bible,which has the OT from Brenton's LXX and the NT from the KJV with slight tweaks here and there. But I heard that the book is too big and the print is too small to read. Other than that, I think the COB is a pretty good bible version for Orthodox Christians. Bible versions with the Majority Text in the NT like the KJV, NKJV, OSB, EOB, and COB are better bible versions for the Orthodox Christian reader.
