The default pinhole is too large for 6x9 (appr. 0.3mm) and I changed to a smaller one (appr. 0.22mm) that gives me much nicer results. Other problems I've had are sloppy film winding mechanism which gives you soft wound rolls that leak light and an inadequate, cheap plastic socket for the release cable.
In what way is 6x12 less than ideal for pinhole work? Aesthetic or optical/mechanical problems?
Holgas are famous for their sloppy winding, leading to fat rolls and light leaks. Some people (not me) consider that a feature instead of a problem. I prefer to unload in the dark. I imagine that loose winding would also be exaggerated in 6x12 vs square, softening and distorting the image even more.
