To this point I've been using this:

/castsequence Consecration, Holy Shield, Judgement, Seal of Righteousness

But I'm wondering, would this work?

/castsequence Consecration, Holy Shield
/cast Judgement
/stopcasting
/cast Seal of Righteousness

I'd like to guarantee that Consecration or Holy Shield are going off every time they can, but in my existing one I'm wondering if I'm missing some of the Judgements and Seal of Righteousness at times.

Also - someone above mentions just using Judgement and Seal of Righteousness in their spam macro (guessing they kick off Consecration and Holy Shield beforehand - but how do you ensure you are using Holy Shield every time you can? Also, is that enough aggro to ensure the healer isn't getting aggro, or shamans/hunters using chain lighting/multishot?

The reason I'm asking is that I notice my paladin burns through mana FAST. At MOST I make it two fights in an instance before having to drink to regain mana. Even bumping that up to three fights would speed up instance runs a lot. (Heck, I guess possibly not using chain lighting/multishot to allow the pally 3+ fights would speed things up alone.)
