If you were building a new deck out #1 southern yellow pine, would use 2x6 or 5/4 for the deck boards? I've been googling this up and down, and still can't decide for some reason. Since someone will inevitably suggest it, I've already considered the various synthetic and exotic materials. Too big for too much $, not happening. So #1 SYP it is. Just need to decide on 5/4 rounded edge or traditional 2x6.
