Maya Animation :: Painting Weights On 2 Very Small Stubborn Verts?

I need to paint the weights of two verts to cling to the middle back. These verts are on arrows that are stuck in a quiver. The quiver is painted to one back joint, as are the top of the arrows. However, the tips of the arrows are painted to the clavical.

 I went into the component editor to try to weight them manually to the back, but in the CE, in smooth skins, they are weighted (1.0) to the clav. I know how to weight a vert to different bones if the CE lists them at the top, but since these verts are only weighted to the clav I don't have the option to set the clav weight to 0 and the back joint as 1. And, obviously, I don't know how to manually add the joint I need into the CE to weight it to 1 and kill the influence on the clav to 0. 

I tried massively increasing my clip plane to zoom in, doesn't work. The paint weights brush just will NOT pick these verts up.
