Monk weapons: Tstaff vs Adamantite/BRS combo

[Silverback]

Hi,
I'm curious what is the better overall setup for monk weapon at 50+.

From what I've read it looks like TStaff is an unresistable stun, 120 DD, and randomly is instant/6second/ or 12 seconds in duration.

Adamantite Club and Baton of Royal Stature have a resistable stun, 60 DD, 6 second in duration.

1. Is my data correct with the stun durations?

2. Any monks reading that have tried both setups and care to comment about it?

I appreciate it
