Thanks LHT-Great to know. May of us just got more and more confused by the various designations, which apparently aren't consistent from decades past and vary a little between companies. I believe Dan's should know more than anybody, and I know you have researched this topic exhaustively, even with that very useful field trip.

Note to self: "THEY'RE ALL THE SAME." Just hone already-I find this clarity comforting as my banded trans and surgical black sit at the ready beside me on the desk for when work gets too much.
