hmm, ive done this 5 or 6 times now,
leaving the 3-6-10 on the lane and then proceeding to throw the perfect spare ball down only to have it take out the 6 pin, leaving the 3 and 10 pins standing there like nothing has happened,
also sparing a 4-6-10, lightest toush on the 6 pin sent it sliding over to fall down just touching the 4 pin which fell just before the spotter came down
my mate has also spared the 4-6-7-10, 2 times, and i saw them both, great shots...
