If I had to pick one pin that us least knocked down, I would say the 10 pin for a right handed bowler and the 7 pin for a left handed bowler but lets just talk about the 10 pin so most bowlers are right handed. The ten pin is the most missed pin for a lot of people even pro have missed the ten pin. It’s just hard to hit sometimes and you need to throw the bowling ball with some speed and if you look at the pros on TV, they miss the ten pin more than any other pin.
