This split is similar to the Big four, except there is another pin included (either the 8 or 9 pin). This split is believed to be slightly easier to convert than the Big four, because sliding the 6-pin over (for right-handers) will sometimes cause the 6-pin to ricochet off the 9-pin and set a crash course for the 4 and 7 pins. Also "shooting the two" (4-7 for right-handers) can work if the bowler can get the 4 pin to glance/bounce off the front of the 9 pin. Statistical review, however, reveals this shot to be the least-converted in professional bowling.
