I used treated posts one time. I had to replace every post I planted. They
all warped and/or twisted. I'll never use treated again. I used cedar
usually and they lasted 20+years. Our local home depot just ran out of the
cedar posts, so I used red wood because I heard the same about redwood. I
know many decks which used redwood last long.
