Drawn in Spring and Persistence are the best. My tests indicates that they deal more than 25% raw damage actually, and the damage over time effect isn't replaced by the one from next hit so enemys will always get all of it. If you add attack speed and potential interrupts(to you...) into consideration Drawn in Spring is superior weapon, it offers better dps to both low and high DR targets than anything else.
When it comes to shield I think that Aila Braccia is the best one.
