Monk Weapons

[cronic]

Hi guys. At what level would it become advantageous to switch from two low delay 1hb weapons to a higher delay 2hb weapon? I have a fighting baton and knuckle dusters now. I would like to begin using a runed fighter staff and later a tranquil staff, but I think the damage cap at level six makes the two quicker weapons better for now. Am I correct? If so, when does the damage cap raise such that I'm better off with the 2hb options?
