I have heard a lot of positive concerning RD1, sounds like it should be incorporated into my toolbox. I am trying to figure out how to add RD1 to my arsenal. Upon approaching a table at a casino what stands out and tells you to play RD1 vs Nor or TB4l. What tells you this is a RD1 shoe and not a sys40, F, OTB4L or TB4L. In other words, why should I play RD1 or add it to NOR. Replies would be greatly appreciated, thank you. John
