Thanks, got my four sticks=2 US (green) and 2 EU style (black)

here is more:
back side of the EU stick (a tiny speck inside the red oval is what sidehack was talking about...nothing, essentially, as far as esthetics is concerned)

Not sure if sidehack has any more more of these, though.
Did not run the sticks yet as I want to use something special with them and just came back from work.
Might do it tomorrow.
