I think wooden poles would be good, but the lenght and if it's sawn timber factor must be taken acount for plus what kind of wood.
Sawn timber dosen't go along the fibers so i must be thicker to get the same strenght as cloven timber/ cut down trees that does go along the grain. And the longer the piece of wood the thicker it must be.
Thats the basics so let me give u a example or two.
My canvas tent that i lived in for 8 months (looked like a small house 2x3x2.5 m w.l.h.) had a external "A frame" of old almost half rotten pine around 10cm thick 3ich m long that was just cut down. That was plenty strong, no flex under heavy snowloads. Example 2 "stegestol" in swedish sort of like a windsor chair in english, the kind thats made of cloven logs, some dryer some more whet, that's crasy strong. Those we made had a ash back with sticks 28ish mm thick in diameter 90cm long, if i wanted i could have used those as a pull up bar for training.
Exemple 3, poles for those times you want to go up stream with your canoe, 5cm in diameter around 2.5m long made of cut down spruce trees. Holds for pushing 500kg canoe upstream a couple of years.
Now if you want a good weight/strenght ratio ash is not the best, norwegian spruce that is a little bit thicker is stronger for this purpose since it has i bit of flex in it.
So if i would have made sticks for a tent tarp set up( as i think you want it) i guess they should/need to be around 150cm long. To get good strenght/wheight ratio for that lenght they would be around 5x 2.5cm thick in a oval shape( round things are stronger but since it's only subjected to downward force the sides need not be that thick) with copper tube fittings top and bottom to prevent splitting, the top ones a bit longer with a hole so a bolt and wingnut can secure it. Everything made of cloven timber , not sawn or just cut down. Sawn for the reason i said before and cut down because it has the core left. When timber dries it gets funky and twists if they are not cloven. Cloven wood is more stable and you now if the woods going to twist or not because you have cloven it before it dries, depending on the pice of wood in a straight or a "twisted line".
They would be a bit heavier then aluminium ones but much nicer to look at and be around.
Hope this can help a bit.
