Venomous Axe on Bards?

[bradsamma]

Alright! So I have a venomous axe on my bard with about 120 dex along with a jade mace and I'm trying to figure out which slot I should put which weapon in.

At low levels when bards get duel wield, I feel like the obvious answer at low levels when bards get duel wield is to go jade mace/venomous axe in the primary/secondary. Does this change at any point? (Or am I just wrong)

Also, how do procs work at very low duel wield levels? Am I still getting the offhand proc (using its equation) as frequently with a skill of 1 as I am at max skill?

Finally, as a bonus, what if anything causes bard songs to end other than stuns, missed notes, /stopsong, and death? I feel like my songs sometimes just end when I'm getting hit and there was no stun...
