The NIBC is by Craig Broyles. He has a little more depth than Wilcock's BST, with a little more of an eye toward the kinds of questions I'm interested in, but it's still fairly brief. You'll find a lot more in VanGemeren (EBC) or Wilson (NIVAC), and even Kidner (TOTC) will answer a lot of questions not dealt with in either Broyles or Wilcock. Broyles is much more recent than VanGemeren or especially Kidner. His perspective seems to me to be a little closer to the moderate or moderate conservative viewpoint. [Full Review]
