Actually, the OB-1 uses a Carbon Fiber Disc under the tip, not the normal vulcanized fiber pad that most people are familiar with.
The Carbon Disc is there to unitize the end of our cueshaft. It is an integral part of the construction, and must stay in place for the longevity of the cueshaft.
As far a cueball deflection goes, it has no real impact on it. The specific gravity of the disc is very similar to that of the tip, so it doesn't really change the mass of the tip end of the cueshaft. Tip end mass is the primary factor in cueball deflection.
Thank you for the information Royce. I got to see one of your shafts close up the other day. One of my friends Ryan Morris bought from you recently. He seems very happy with the way it plays. When you say unitize the end what do you mean by that.
What I mean by unitize is to tie everything together. At the end of our shaft we have 3 different materials coming together and the carbon disc ties them all together for a unitized strength. As a matter of fact, I use one for my break cue and I have others out in the Dallas area being tested right now. The OB-1 seems to be very well suited for the break shot because with the very low deflection you get it is much easier to contact the rack square. If the tests go well, we may offer them for break cues.
