I've yet to see this fail, even with a well worn tool. (except on English 3 speeds, but I've made a special tool for those.)

That's a great idea! I never thought of that, but I bet it does work well.
I finally broke down and bought a very heavy-duty, generic cup-remover-tool on ebay. I forget the brand name now, but it's a fine tool. Two pieces that thread against each other, and down onto the cup. Flats on the ends of both pieces. Clamp frame in work-stand, support the rear-triangle with your legs or knee, use a large adjustable wrench (at least 8" and 12" is much better), and start crankin' on it. This has yet to fail. But you have to find the tool. They're around.
It was worth the investment in my case. It's saved me a lot of time and frustration.
If the cup becomes locked so tightly in the tool that you can't unscrew the tool from it, place in a stationary vice, and use a big wrench to loosen.
The other nice thing about this sort of tool is you can use it to properly *tighten* a fixed-cup, simply by torquing on the opposite side of the tool. Very clever, actually.
My memory is vague here, but I suspect the tool I have is not dissimilar to the Campagnolo tool, but I could be wrong.
