How do you aim fast-speed or sliding-ball bank shots?

The most accurate system for aiming fast-speed or siding-ball bank shots, where the OB has little or no top or bottom spin at the cushion, is the twice-plus-tenths bank shot aiming system. It is based on rail-groove measurements across from the diamonds. An alternative through-diamond system is the 1-more-than-twice system. Both are demonstrated in detail in the following videos:

Other useful systems for aiming sliding banks, including the Schofield 8-10-12 system and the Briesath diamond-connect system, are demonstrated in these videos:

For more information, see “Large-Angle Banks” (BD, December, 2023).

Other alternative through-diamond systems for fast-speed banks that use a different numbering system for the diamonds are demonstrated in these video: first, second. The first uses 4, 8, 12, etc. on the origination rail, and 10, 20, 30, etc. on the target rail. It can be referred to the 4d-to-10d system, where d is the diamond number (1, 2, 3, etc.). The second uses 2-4-6-8 reference points and 11-15 diamond numbers.

In addition to being able to use the aiming systems above, there are advantages to using fast speed with bank shots. For more info, see: advantages of fast speed.
