While this will rock on my Shamie, I can't imagine using this on Yark. It's like "I'll have one spec set up for optimal Raid PvE performance and the other will.... ummm.... ahhh.... errrr....."
(but nice if you PvP I suspect)
If nothing else, you can set up different glyphs on the second talent tree. I almost considered going resto on both of my shaman's specs with different glyphs and slightly different talent choices (one for raid healing, and one for MT healing), but I already have a fairly impressive enhance set built up. For you I think though, your secondary tree should be destruction if it isn't your primary tree, because it will provide Replenishment next patch. Then again, so will frost mages, survival hunters, shadow priests, and ret pallies.
