I once spared the 8-10 three times in one night (once in the first game, twice in the last game) in a team that left 5 of them in one night and spared all five.
It was on 21-22, and we worked out that if you shot down the 2nd arrow on the left on 22, and hit 2/3s of the way across on the left side of the 8-pin, it would bounce off the kickback and up the gutter every time.
I got all three of mine the same way, Gavin Hawkes - a lefty - left one flush in the hole, and fired at the 8-pin and it did the same thing - spare.
Then Adam Carr left one and tried to hit it in the same spot, pulled it and almost totally missed it, it nicked the 8-pin lightly, sending it sideways taking out the 10-pin :lol:
