It's hard to say trumpy. There are alot of Zodiac staves in the market at the moment (due to the weekend event we had not so long ago). I think that the req 10 combined with the 9% HCT will hinder the price alot more than you might imagine.
I'm humming and haaring as to what you might be able to get for it. I'd say around 10-15k because of the imperfects on it and the fact that it is a ritualist item (not saying there aren't any rits out there, it can be a little bit hit and miss with rit items at times.)
As usual get more opinions and I hope this helps you.
