OK, i picked this up, two yrs ago,
I did it, by throwing my ball as hard as possible, which is slightly slower than Maximum Bob, well i hit the 10pin, slightly on the gutter side, and the pin kicked into the pit, and bounced out and deflected off my ball, and kicked over and hit the 7pin, and happend so fast, most people was shocked, cuz they couldnt believe what they saw, but, it happens, and i have gone after the 7-10 like this several times, and have come close everytime too.
