Weapons for monk - what is best?

[Lhancelot]

I realize 2hb is the way to go, at least that's what it seems when carrying a T-staff, but when does this become the best weapon to use for the monk? Only once it procs? Or, is the dps surpassing 1hb DWing even earlier than that?

Aside from this question, I also want to know what 1hb weapons are best?

I seen on p99 wiki, monk weapons the Stave of Shielding is listed as better dps than the Adamantium Club, yet, I always see the combination of Ad Club and one SoS being used.

If SoS is better damage due to ratio, why do monks not dual-weild Staves of Shielding? Is the Ad Club mixed with a SoS due to it having a stun proc, and the slightly less dps is given up for the proc effect?
