Optimal BRD rotation?

[Saseal]

I have a fresh 50 BRD thats been sitting for quite a while (lets put it this way - I still have myth gear on him). I took him into Labyrinth and ST for the first time (dozens of times on WHM, so I'm not new to CT) and found it's pretty damn fun in 8-24 raids - playing songs when I see it (Ballad for WHMs/SMN on mid MP or after a raise, Foes for BLMs in the group, Swiftsong for the running between) and so on. So I'd like to play it a bit more.

But I don't know - as I main WHM - if theres a particular rotation I should be doing in the meantime.
So, I'm asking, ss this a viable rotation? Or is there something in particular I'm missing/don't know?

For Raids/Trials, I've been scrubbing together generally this:

At pull start:
- Internal Release
- Raging Strikes
- Flame Arrow
- Windbite
- Bloodletter
- Venomous Bite
- Heavy Shot
- Straight Shot
- Repeat Heavy and Straight
- Repelling Shot when it's off CD (but I'm a bit forgetful about it)

This is with weaving in Blood Letter if and when it pops up, between CD and when it resets itself + refreshing DoTs and Rain of Death if in with those trash mobs between bosses in CT. I've RoD'd bosses for the debuff but I don't think it's particular debuff (lowers evasion) is helpful when most are geared these days.

My reasoning for Raging and Internal at start is getting the DoT/flaming arrow blathering out damage from the start, and still using Hawk's Eye as a backup damage buff (unless I'm misinterpretting the skill descrip?) to keep some damage high while IR and Raging are on CD. I tend to re-use Internal in between (faster cooldown).

....After IR and RS goes down, then:
- Hawk's Eye
- Barrage (for the in-between auto attack hits)
- Re-apply DoTs when needed under Hawk's Eye
- Rinse and repeat Heavy and Straight shot
- Rinse and repeat weaving in Blood letter

Repeat rotation(s).

At enemy 20% HP (not mentioning DoTs/buffs as it's dependent on timing):
Quickly consecutively:
- Heavy shot
- Misery's End
- Straight Shot
- Blood Letter
- Heavy shot

In dungeons I've used generally the same rotation on mobs/bosses, but additional Rain of Death in mobs and Quelling strikes if I see my threat meter getting high (being WHM main, my eyeballs tend to habitually drift to the party list).
