I'm posting this here for our Prot Wars (including myself so I don't forget!) to assist with maxing out SnB procs for SS.
Power Auras Classic (WotLK) is a useful way to watch when your SnB procs to ensure that you are maxing out your rage-free SSs according to a post I ran across on Tank Spot. I haven't tried it out myself yet, and I'm not sure if SCT's listing of auras/buffs might not do the same thing. But the original poster found this very helpful.
If you're on the PTR, give this a whirl and let me know what you think about it. I've always viewed being on the PTR as a waste of my time as I have things on Live that I want to build and work on. So if you're there, post a heads up for the rest of us.
