In this range (14"/355mm - 360mm) there are really only three commonly available choices for 12X20 and 14X17: 360mm Symmar Convertible, 355mm G-Claron, and 14" Goerz Dagor. I have owned all three (including three different 14" Dagors) and for my money the 360mm Symmar Convertible is the most desirable. And that would be true for me even discarding the fact that it is also convertible.
I also have a couple barrel lenses I want to test; a 360mm W.A. APO Nikkor and a 360mm APO Gerogon. The Nikkor is rather uncommon, but the APO Gerogon is plentiful and inexpensive. Both are f9 process plasmats similar to the G Claron. I don't know if they cover as much as the G Claron. Both should cover 7x17 with ease and are reported to cover 8x20 - which equals about 72 degrees of coverage. 75 degrees is all that's needed for a 360mm lens to hit the corners of 14x17. So, one or both might squeak by at small stops. I guess I'll find out when I get around to building the 14x17 conversion kit for my Franken-ARCA.
I've rigged up a Sinar shutter for the front end of my camera that makes it easy to use/test barrel mount lenses. The ability to easily use barrel lenses with an accurate shutter opens up a lot of possibilities for affordable ULF lenses - especially the longer process lenses that are both plentiful and relatively affordable.
