I think my issue is that, at level 1, you're going to need to pick up at least two maneuvers from Tiger claw if you want to have more than just Sudden Leap. I'm not planning to be TWF, so that leads into me being less keen on grabbing wolf fang strike. But that boost removes my having to pick between circles (the two I picked are both very good, though I think I'd want Searing Flame for better damage.

That would work quite well, I think. I might drop it from Enhancement to Attack and Damage and instead make it elemental damage matching your primary circle? Of course, this is because Necklaces of Natural Attacks exist, but that might push damage too high.
