I try not to stake any of my flower spikes.
I use a tiny bit of silicon in my fertilizer to give flower spikes strength (apparently).

explains how much to use (ie roughly 8 ppm Silicon)
I've not had one fall over yet.
They always grow towards the light so I turn the pot whichever way I want the spike to grow. You want it to grow straight up? Place a light source directly above it...
The flowers also mostly orientate themselves in the direction of the light so when they open most of them are facing the light source.
If they want to grow into the pot then just placing aything underneath to lift it up as you have done is what everyone does. If you wanted to stake it which admittedly I might have to start doing with cymbidiums then Camilles approach with a straight stick in the substrate and something to tie it to the spike is what I've seen done.
