But this is only for if someone wants to be nit-picky about stuff that doesn't matter much. For instance, I haven't read a version that says Jesus isn't the Son of God or that Jesus died for some other reason besides our salvation. I'm talking about little stuff.
The 1984 NIV is very readable and OK on accuracy.
The 2011 NIV is best deposited in the nearest round receptacle. It is a politically driven, gender neutral translation that is torture to read where it has been mangled.
