I think you have the wrong SpellId. Heroic Strike is -> http://www.wowhead.com/?spell=78 . Looks like 41975 goes to a Heroic Strike that's used by a Black Temple mob? Maybe it doesn't matter. Also, this is overly nit-picky, but the Glyph of Revenge makes your next Heroic Strike cost zero rage, not be instant.
Yeah, correct regarding instant vs zero rage, sorry. As for the spellid, I captured the number from the combat log using one of my mods that sounds an audio alert for various auras. Couple that with the fact that inline aura is now showing a timer on heroic strike after revenge, it's working to my satisfaction :)
I really can't say enough great things about inline aura. I absolutely love it on my lock. It's an excellent interface that doesn't clutter the screen with timer bars.
Forgot to mention, I added Shadow Trance procs giving instant -- yeah, instant this time, not free :) -- shadowbolts with:
SelfTalentProc (47809, 17941) -- instant shadow bolt from Shadow Trance procs
