well, I just scored a Wollensak 159 F12.5, with the purple dot, single coated, off a kind soul here on APUG. I'll throw it up on the 8x10 when it arrives and see how it behaves. The killer for the 5x12 format is NOT the camera (although that's not cheap). It's the film holders - $275 each!
Thinking of which, I think it might have been in your article in View Camera, Kerry, but it may have been elsewhere, I recall reading something about the Shen Hao 5x12 needing a minor modification to make the film holders fit accurately. Am I remembering this correctly, or am I smoking weed unbeknownst to myself and wandering arond in a fog?
