Nuke and Vray passes
So I'm playing around with the PLE of Nuke to try and get a hang of it, as well as to see what it's all about. I was wondering, for an animation I'm working on I'm using Vray Render Elements and saving them out as 16bit multichannel EXR's (I can't afford the space a 32bit takes up).
One end of my question is this, which are the best elements that I should be selecting? Which benefits more, a raw pass or a regular, such as rawShadow versus Shadow, or rawGI vs GI. The main passes I'm going for are: Diffuse, GI, Shadow, Reflection, Refraction, Lighting, AO (vrayDirt), Velocity, and zDepth. Are there any other ones I should consider?
The other part is, is there anything I can do in Nuke to tweak or enhance my GI pass to make it less grainy or am I restricted to the actual render settings in Vray?

16bit openEXR should be fine, we use that all the time.
If you just want to create a beauty with the base elements, the passes I use are:
And if I have this in my scene:
Just create a merge node (M), and set it to plus.
If you want to recreate the light with light selects, remember to disable lighting and specular.
