I think there is a new version of the Holga panorama, one that is not the pinhole version. It's available from Freestyle, but I didn't see it in B&H. There is also a "35mm adapter" available; it looks like a pair of shims. That means I won't have to use my homemade shims! I used those in a regular 120 Holga. Yes, I have to unload in the dark, and I have to count clicks to advance the frames. It's all part of the process.
So, has anyone used the non-pinhole panorama? Anyway, I'll be sure and check the tripod socket.
