Well, you can get away with cutting corners once in a while, but sooner

compilation will be far superior.

You're a cloning stud!  However, since the original poster didn't say
what restriction enzyme he was using for blunting, I thought it best to
send him the "long" procedure since Cip isn't always fully active in all
restriction enzyme buffers.
