I find the more rigid ring to be more useful than what Scott describes in comparisons. BUT you have to anneal the ring material in my sample.Scott gets immediate results. I would be somewhat suspicious of an unannealed sample as I recall the Ed Skeels pull tests. I still make a Hagy seal if there's any doubt and the doubt usually comes with making new forays in color. The main point is that all the indicators should be pointing in the same direction.
