Play with that reef, and you'll find itI think can make a huge difference.
I think you misread my post. The Cringle is only 6" closer to the mast than the clew. It's a few feet above the boom. I've has a main with a flattening reef, but that's not what I'm taking about.

I just don't see a reefed main being any different than a loose fitted main. Similar forces in similar places.

Correct, except for the relatively minor point that on a reefed main the load is (usually) spread to two points - a sheave on boom end and a 'tie around the boom' under the reef point - while with a full loose foot the clew load is (usually) slightly more concentrated (on a track or on more modern booms a spectra webbing around the boom, and the outhaul). But this slight difference is unlikely to be enough to make a structural difference/problem except perhaps for the very most highly engineered carbon racing booms.
