Are jump sticks allowed at the U.S. Open ?
VAPoolPlayer is correct in that jump cues were allowed at the U.S. Open!
The ongoing debate relating to jump cues continues and is the subject of many a heated threads.
Old-school players did not welcome the advent of the jump cue and still feel to this day that it ruins a perfect safety play. The new generation of younger players, however, maintain the stance that jumping a ball requires a skill, just as much a skill as executing a safety.
On the regional tour scene in my area, the Viking and Planet Pool 9-Ball Tours allow jump cues. However, the Joss Tour rules allow one to jump balls ONLY with the player's shooting cue. In some venues, like the Reno Open, jump cues are prohibited.
When a ball is jumped correctly, there should be no damage done to the table. Sometimes, though, Newbie players or those who haven't perfected the jumping technique correctly can hurt the table. Not a good thing, especially for pool room owenrs wanting to maintain their equipment in the best possible shape.
At the recent Skins Billiards Championship in Atlantic City, NJ, I saw Charlie Williams practicing, and he executed what looked to me like an impossible jump shot.
The cue-ball was frozen to the ball he wanted to jump over. He whipped his jump cue out, raised the butt end very high, looking almost like a 90-degree angle from my vantage point, and the cue ball hopped over the ball like a leap frog, making contact with the object ball, which then slid in the pocket.
There is a right way and a wrong way to jump balls. It is an art form and beautiful to watch when done correctly.
I recently heard Allen Hopkins state that the Frog jump cue is a great tool for jumping balls and is an excellent value, very easy on the pocket book for the aspiring pool player as well as the pros!
We've currently got a Bungee jump cue in my camp. The Sledgehammer break/jump cue is very popular as well. Mike Massey has a custom-made jump cue in his bag of tricks like no other I've ever seen. Each end of the stick has a ferrule which performs differently, depending on the situation.
