I am planning to build a rolling log to help my chanses in ninja warrior?

and what would be the best materials. Wood or a hybrid of iron and oak?

Answer:
I would not use iron, as it would rust. Plus, it is pretty heavy, so it may not float like you would expect. Wood should work, at least until it rots.
