Glad to have another craps player aboard. I don't believe you were around for previous discussions of dice control. So just so you know, I was barred from shooting (since revoked) and no longer consider myself a dice controller due to lack of practice and minimal actual playing time. However, to answer your question, in the day, I had several different sets, but the primary set was the left die with 6 on top and 3 facing me; and the right die with 3 on top and 6 facing me. Grip was middle 3 fingers with thumb on top. The key to the throw was the release of the thumb at the right time to get proper revolution, and proper arm speed and range which is where practice and repetition is required. Also, there was different height for different numbers if I was at that time in good control of the revolution.
I never liked the backhand toss (and I know most dice controllers prefer it) because when I did it, it had too much spin. When I was in good control with the understand, there was very little bounce back or roll. I could get a pretty flat landing if I was on.
