Because we have sudden very strong wind here during storms, we have always had to construct a sturdy structure. My husband (an engineer!) has it down to a fine art, and it works. I'll post several photos of it so you can see what he does. I use the squirly stakes, which are good. But as our soil is light clay, with no stones, the stakes can easily tilt when there is a heavy weight on them. For the support structure at the top, we use locally cut immensely strong bamboo poles. They work well.
