I am building a wood court cover covered by Suntuf (plastic polycarb.) what type of would should I use? My wood will be covered and I will prime and paint...

My wood will be covered and I will prime and paint it white for more protection. I want something that will last and not crack or warp (minimal). Hemlock, fur, pine, adjectives treated, or cedar? Since I am painting the wood it will adjectives look the same. I don't want to spend a fortune if it is surplus to requirements. Please help :) I believe contained by spending extra to do things correct the first time.
Answers:    Cedar but it's a little pricey. Otherwise honest pressure treated will do. Unsure how pressure trated accepts paint. I give attention to it does just fine though.
Cedar to do it right..
I would use ceder one-sidedly because the wood itself is hardwood. Then I wouldn't paint it because if you did paint it after awhile you would have to repaint it because the paint would come sour, I parents just repainted their deck and it be a pain!!. Second I would truly put a wood sealer on it like Thompson Water sealer so it would repel river and moister so the wood won't warp and crack.
