Very well said Pinwheel 12. I' m with you 100%. Before the 11-ring there were only a very small handfull of perfect scores ever shot. A perfect score with 11 rings is virtually impossible. In bowling a perfect score of 300 happens somewhat regularly. You won,t see them adding an 11th pin to up their challenge. What' s next? a tack size 15-ring inside the 11.
