Ted what you are seeing between Sandy and me and no doubt M o R too is a minor difference in detail nothing more. It is no different than you deciding to wear a straw hat to keep off the sun and your neighbour, just down the road, choosing to wear a "John Deere" hat. It is only details that we are talking about, not the basic principles. Thank goodness for these variations of the same theme, it would be no good if we all dressed like peas in a pod, now would it?
