Herringbone struts are far superior to solid noggins but will take a
bit longer to put in. The problem with solid bracing is that any
shrinkage in the joists will cause the noggins to loosen causing sqeaks
etc, whereas with herringbone stuts any joist shrinkage ( which is
mostly across the grain i.e. reducing the depth ) will actually tighten
the struts. I've recently had to take up two different wooden floors and
then glue wedges into solid noggins to stop them sqeaking. Its a fact
that a lot of sqeaking floors can be traced to poorly fitting solid
bracing.
