It's amazing what archaeologists will debate as a subject-what's next? best pencil sharpeners, knife or a proper pencil sharpener?
I've found that there is a place for both a wooden frame and concrete reinforcers- wooden frame are light weight allowing them to be used for balancing on delicate features (whereas a metal one might be too heavy),but the string is prone to warping (same as the wood)and breaking, and a metal frame is more durable so can be used more accurately (unless your on a site where the idiot in a JCB runs over it) for longer.
Frames are also great on large complicated sections-instead of measuring from your stringline,you put pins along said line and hang the frame up on it and draw like a vertical plan!!
