Leveling Solidfaith as Shadow

I've broken down and decided I just can't do it. As much as I wanted to level as Holy, I have to give up on the idea. DPS too low, downtime too big.
The difference, once I specced to this 9/0/53 build, was night-and-day (fitting metaphore :)). I didn't manage a lot of quests as Shadow before going to sleep but in the ones I did do, the mobs dropped like flies.
