From page 43 of the manuel:
32. EQUIPMENT
In general, any piece of equipment designed specifically for pocket billiards,
with the exception of laser devices and mechanical cues, is acceptable in APA
League play. Some specialty cues (see SPECIALTY CUES described in
definitions) may be limited in use. Special equipment, such as bridges and cue
extenders, are legal. You may change cues and/or cue shafts during a game
provided the cues and/or shafts you are switching to do not violate any rules of
use, and you remain within the Time Guidelines (outlined on page 7).
Jump Cues – A specialty cue designed for attempting jump shots (see JUMP
SHOTS described in definitions). They may not be used to perform jump
shots or massé shots (see MASSÉ SHOTS described in definitions) in
standard APA League and tournament play.
Break Cues – A specialty cue designed for breaking (see BREAK SHOTS
described in definitions). Sometimes combined with jump cues to form a
jump-break cue, these cues are allowed in APA play for breaking. They may
not be used to perform jump shots or massé shots in standard APA League
and tournament play.
Regular Shooting Cues – Any cue designed to shoot the majority of shots in
a game of pool. These cues may also be used to perform jump shots, massé
shots and break shots in all APA League and tournament play.
APA will rule upon any piece of equipment in question that is not covered by
this rule.
This rule is not very clear to me. It does seem clear that you cannot use a specially designed break cue (or J/B cue), like the Predator BK or OB version etc,, for jumping. However, if (like me) you break with a "Regular Shooting Cue" upon which you have put a super hard tip (so that don't in fact use it for regular play), I think this rule would allow me to switch to it and jump.
The rule really should be clearer, IMO.
