What do you consider the best recently developed LF accessories?

See my accompanying thread. I consider Readyloads and the Gnass Ready Load File to be two of the best. Lightweight and convenient, I can carry far more film in a organized way than I ever could before.

And also........Carbon Fiber anything. Between my camera and my tripod. my arthritic joints applaud.
