I'm looking at buying an Arca-Swiss F-Line Compact large format camera and am looking into using it for 4x5, 6x9 and 6x12 film formats.

My understanding is that Horseman has one of the best rollfilm backs on the market for 4x5 cameras.

First of all, is there anyone that uses this combination? Does the Horseman rollfilm back fit perfectly on the Arca-Swiss F-Line Compact? Is there any other brand that holds the film flatter or is of better quality?

Your help is appreciated.
