N00b Rotation Question - Trick Placement.

Here's my usual rotation while out in the world questing. I am level 38 at the moment. This is against a single mob.

Stealth
Reveal Weakness
Distract
(Burgle)
Aim (I have the trait)
Surprise Strike
Burglar's Advantage
Next Crit Chain Skill (can't remember name)
Subtle Stab
Cunning Attack
Trick (of some kind)
Improvise from there on.

Sometimes I throw the trick in right after the crit chain if I am taking lots of damage or something.

Here's my question - should I throw up a trick right after my from-stealth SS or where I am currently doing it?

Is my rotation completely borked? Am I otherwise doing it wrong?

Oh I believe I am 4QK, if that makes any difference.

Thanks in advance!
