The list is long but none of them deserve the honor.
I may just stretch them between the saplings.
If the weather will dry, I have cedar logs down in the woods to get out. I will have one at our house before long.
I love working with cedar for non load bearing use.
I think a grape arbor of cedar would be nice after the cross.
I gas easily enough using an axe, no longer fit as I should be but the satisfaction is worth the delay.

Cedar is fun with an axe. Grape arbor is excellent idea. My son and I have enough logs for a small camping structure or run in shed.
Try some black locust, too. Green it cuts nice and might do better in some structural applications. The trees will just die of disease before they get real big, so you might as well use it. Just work it green, once it dries it is like rock.
