I think the key is in the timing. That's the biggest factor that made all of mine doable. It always ended up that when I THOUGHT I had enough timing in it, I never did. Once I got it straightened out, all was well.
That and not "over" camming the thing in the first place
I think a LOT of us tried to run too much advance curve and not enough initial. "Back when" I ran a dual point, I ran for quite awhile with NO springs, the points would "drag" the advance back to start. But it still had a "factory" (HP hemi tach drive) curve, so it was still to long to allow enough initial advance.
