Thank you for all the response.
I am very interested in some comment regarding being able to jump really close with a jump cue. Is that really the most important thing to look for in a jump cue?
I designed the X jumper to be a very accurate jump cue, with almost no vibration. When it is used at the table for testing, I noticed that even if the player missed a jump, the cue ball did not spin, which meant the miss was due to incorrect body alignment and/or stroke, not because of unwanted English that a lot of jump cue tends to add to the cue ball.
I want to make it clear that I am not a believer of a jump cue needing high squirt and a break cue needing low squirt. I think in order to have more power for both jumping and breaking, a stronge tip, and a well designed taper and balance is very important. In my opinion, a hollow front end might help to reduce squirt on a bad hit (so will hitting the ball softer

) but it will certainly compromise on the power generated ecause it is not going through the ball (it is buckled).
When I designed the X Breaker, I wanted it to be a cue good at both tasks. I do not believe that it is impossible.
On the other hand, as I have gotten to know more players, and have a larger number of pro players and champions using the X breaker, I started to see things that I did not notice before.
For one thing, Ralf Souquet told me there is usually a 30 sec time clock in pro events, so taking down a jump break cue could be a bit inconvenient. It sounds like a joke, but at his level, it is not. It requires intense concentration to play perfect pool, and it is desirable to be able to stay focus at all time during a match.
Also, to tighten a jump cue back to a jump break cue is also time consuming, not to mention there is a chance the cue might not be tightened up properly. One bad break can cost a pro player to sit out the rest of the match, so the break/jump is more important than I used to think.
It is nice to be able to jump a chalk away, but most importantly, for the pro players, it can make a hugh difference if they can jump and make the ball, or just jump and hit the ball. To be able to keep running out is the forumla for winning, so a jump cue needs to be very accurate. Again, one bad jump can cost a whole match. Think about Chao in the last match with Busta during the challenge of champion--what happened if he missed that jump?
As I am sure most of you notice, hardly will you see a pro go for a jump a ball away, and hardly will you see them jump with a dart stroke. I did not notice this until I started having lots of players using the X Breaker on TV and in major tournaments. They have offered me very valuable feedback. They told me the pendulum stroke is a stroke built into their muscle memory, it is therefore a stroke they like to use and repeat with confidence.
I think in that sense, the X Breaker has evolved to becoming a jump break cue built and designed for the better players, since it has adapted lots of feedback from various champions over the last two years.
Tony Robles told me the X Breaker was the most accurate jump cue he has ever used, and I am very thankful for his compliment.
I have built a new jump cue which weights only 3.5 oz, but it is not a good tool for players who play to win consistently, because it is not super accurate. So, I have put that design away.
I personally can jump a ball and a half away with the X Breaker jump portion consistently, and it is good enough for me. But I have received requests of offering a jump cue seperatly, so the players do not need to take the jump break cue down for the jump. I am also hoping more people can afford to enjoy our new tip technology through using our jump cue. I think the X jumper has a bit lesser vibration, and is even more accurate on longer jumps, with a better feedback.
I am afraid I am not convinced that a jump break is a compromise in terms of performance as I do not see "jump" and "break" having contradicting requirments. However, I do feel that a jump cue and a break cue seperately might be more appealing to a certain market, and I am very interested in the feedback from the memebers here in that regard.
Thank you.
