Is it best to screw the speakers to the stands or just sit them on top of the spikes?

Use Blu-Tac to stick your speakers to the stands

If your speakers are designed to be screwed to the stand then that's the way to do it.

If not then Blu Tac as suggested.

Sitting them on spikes wrecks the finish if they are moved slightly.

I use spikes for my rears on mission stands, no problem.
