I used an L- cleat nailer on my 700 sq. feet -- and noticed, as I installed, that some tongues were splitting off a bit. I didn't think much of it, as it wasn't breaking right through the wood.
Three months later I have snaps and pops that come from spots of the floor when I walk over them, where the tongue broke free of the rest of the board.
I wish I had used staples-- even though some people say they don't hold as tight. Not sure who I'll fix my problem with the popping, etc. Perhaps I will ignore it, as my wife says I'm the only one who notices it -- the house is almost 50 years old and has its own fair share of creaks and pops.
My blog chronicles the decisions/install:
