How do you keep a met post straight as you wallop it into the ground so

It's difficult. You could try getting a length of steel such as a
*thick* piece or re-inforcing bar, or similar round stuff, and then
hammering that in to make a pilot hole.

I wouldn't use Metposts for a 6' post unless it was for a very
well sheltered fence, or a possibly corner post, or for a "non-
solid" fence that lets the wind blow through. They're useless
osds, 'though someone will always put their hand up & say they
were OK for something....
