I have a Z-2 shaft which I've previously used with my Viking. Check out my post for photos and details. Let me know your best offer.

I have a Z-2 for Viking. It shoots straight and it has ultra low deflection.
The only reason i'm selling it is because I'm looking for a longer cue.
Let me know if you need it.
