Skuda Uaezdaettae (Scythian Noble Cavalry)

[Zlovie]

Well, as I have currently started a game with Pontus, I would really like some clarity on which weapons these guys use.
I had always assumed they used their bows, but as I read this * in the unit description (on the EB site) I start to doubt that.

*Now, the Skuda Uaezdaettae, or Skythian Nobles, fight in a matter almost more similar to the Greeks than their nomadic ancestors, preferring the xyston or spear and sword to archery, even though they still carry composite bows.

But do they use their bows? If they do, they would be pontus' ultimate heavy cavalry :D
Then they would be worth (at least to me) to built type 3 government instead of anything better...

thnx in advance
