I would argue that a bit - moving spikes are pretty ineffectual because they end up just pushing the robot away as the armour is stronger that their traction.

On the other hand, just plain static spikes can be very useful particularly where they are used to grip an opponent in some way like on tornado or big brother.

In general though unless you come up with some novel take on them, I cant see a pnuematic spike ever being successful in a vapour.
