Looks like 8,9,10, is the best group. With Retumbo. Same with H1000. You will usually see 2 nodes 1 at the lower end of charge weight and 1 at the higher end.
I was asked how I identify. Told them i'm 65 don't start that B.S. That stopped the line of B.S questions. ASk me questions about my health not my life.
