Actually, that's not what he said. He said *as long as the angles match*, a small difference in *diameter* doesn't matter. It seemed to me from looking at what happened as I tightened the stem bolt that a mismatch in angles would be bad for the head tube, because the corner of the wedge would get tightened into it, rather than the whole side.
