Wyoming fence guys compare foam, wet set and dry set concrete.

They claim the utility guys are using foam in their posts.

Looks like wet is best but foam isn't too bad.

They were planting steel poles. I would think that if you are using wood, the post is more likely to fail than any method, provided it's done correctly.
