I recently ordered a X Breaker from Joe at Nielsen's Billiards. He's a great guy who I highly recommend doing business with by the way. I also talked to Richard who makes the X Breaker throughout the transaction. I can definantly say that he is a stand up fellow who stands behind his product 100% and would never hesitate to buy another one of his products!
I received it last friday and have played with it a bit since then and wow, I'm impressed
It was definantly worth every penny I paid for it. I was using a Players jump/break cue with a plain leather tip on it before for reference. I also have borrowed a friends sledgehammer several times.
I personally feel like the X Breaker gives me a better spread on each break. Also, I must comment on the tip on it. I don't know what that thing is, but its pretty crazy. It chalks up much like a leather tip and holds the chalk every bit as good. It also grips the cue ball very well. Running balls with it and using english is actually no problem with it. Sounds a little funny, but works
My old jump/break cue was 19oz and I ended up getting the 18oz version with a few weight bolts thrown in by Joe. After trying it in a few different configurations (18, 18.5, 19), I have come to like it at the 18oz weight.
Also as odd as it sounds, I find it easier to jump with the cue whole rather than broken apart. Yea, I know... I'm weird
This is where I felt even the added ounce made a difference and I was able to get the cue ball up a bit faster with it at 18oz. Also, after a bit of practice I was able to control how much draw I could get on the cue ball when jumping it. This allows me to get a much more controlled jump shot instead of the cue ball flying off after hitting the object ball. This coming from someone who was doing good to clear a piece of chalk before 
Of course the first thing I did with it when I got it was rack up a 9 ball rack and hit it with everything I had
Did I mention that the tip grips really well?
The first thing that really jumped out at me was how much spin was transfered to the cue ball from where I hit it off center. No miscue, just the cue ball flying/spinning around the table wildly after breaking the rack.
After a bit of practice with it, I'm able to get a much better spread on the rack. My position after the break still leaves a bit to be desired
... but that is my fault, not the cue's. The extra grip from the tip on the X Breaker has shown me a few flaws in my break stroke that I still need to work on
I also have a consistent jump shot now I can use instead of always having to kick at balls.
I know that's a bit long, but hopefully it will help someone else considering the purchase of one
Cliff Notes:
Worth every penny
