14.1 -- Under WPA (world standardized) rules, the equipment specifications apply for 14.1 the same as for 8-ball, 9-ball, and 10-ball. The only requirements on the size of a cue are that it be at least 40" long, at most 25 oz. in weight, and at most 14mm in tip width.
One Pocket -- The WPA does not have rules for the game of One Pocket. Under the "Official One Pocket Rules" published by OnePocket.org, the rules on jumping are as follows:
"Players may use jump shots in One Pocket as long as they are performed with the player's own standard playing cue using legal jumping techniques as defined in General Rules. Specialized jump cues are not permitted in One Pocket.
Please note that many players, poolrooms and tournament directors have differing opinions on specialized jump cues. It is recommended that players check with their opponent, the 'house man' or the tournament director prior to an important match to come to agreement on whether specialized jump cues shall be permitted or not."
Wow, frost pulled out a jump cue on reyes during their race to 8 match. When reyes said they were illegal scott says they are ok. Reyes let him shoot with it. And by the way, Efren has one and so does Earl.
