Id like some recommendations for a 6x9 roll film back that I can use in a 4x5 v iew camera (Super Speedgraphic). Yes I know, my Calumet catalog is in the mail, but Id like some real world experiences. Id prefer the type that has both sp ools at one end, so I can slide it under the ground glass. Ive heard that Camb o makes one; any others?

Thanks in advance.
