Crown Graphic Ground Glass Alternatives

[Johnny Reno]

I want to use fujinon A or Schneider G-Claron lenses in marginal light. These are great lenses but f9 is very tough in low light. I have the stock ground glass with fresnel lens and the focusing hood from the view camera store. What and where is a better or brighter ground glass? What are your experiences and suggestions?
