Each shaft is 11.75mm Tip Diameter, OB-2 Special Pro Taper

You should play with the OB-2 because it is the best shaft on the market. The OB-2 shaft has the best combination of the four primary characteristics affecting shaft performance:

• Low cue ball deflection
  "Cue ball deflection" is the phenomenon that occurs when the cue shaft contacts the cue ball left or right of center ("English"). Instead of traveling along the center line of the cue stick, the cue ball will travel down the table at an angle to the line on which the cue is pointing.
  
  When using side english, "Cue ball deflection" must be compensated for in your aim. The more you have to compensate, the more likely you are to miss. Since side english is often necessary to play position on the next ball, "Cue ball deflection" is something we all have to deal with.
  
  "Cue ball deflection" is affected by the weight difference between the tip end of the cue and the cue ball. Obviously, we can't change the weight of the cue ball, so we focused on the tip end of the shaft. By reducing the weight of the tip end of the shaft, we have reduced "Cue ball deflection". The OB-2 tests virtually equivalent to the lowest deflection conventional taper shaft on the market.
  
  Combine low "Cue ball deflection" with the other benefits of the OB-2, and you have the best shaft on the market. 

• Good overall shaft feel
  
  By far, the comment OB-2 Cue Shafts get most often when people hit with the OB-2 is how good it feels. Recently, a highly respected BCA certified instructor said, "It feels like a single piece cue." Comments about the feel are even more common than comments about deflection.
  
  "Exceptional feel" is not an accident. To start with, the tip end of our shaft is solid wood, including the ferrule. Secondly, the central core of the OB-2 is composed of vibration and sound dampening material, which contributes to the excellent feel. Finally, the construction and taper and radial consistency of the OB-2 add to this exceptional feel and provide an extremely consistent hit.
  
  Good performance and good feel are no longer mutually exclusive.
  
  Combine this "exceptional feel" with the other benefits of the OB-2, and you have the best shaft on the market. 
    Exceptional playing consistency
  
  The patent pending design of the OB-2 provides for an extremely consistent cue shaft. When the cue shaft performs the same every time, a player becomes more confident.
  
  The OB-2 shaft is constructed using six "stress relieved" segments. Each of the six segments is made of laminated hard rock maple and is machined in a manner that removes the internal stress. "Stress relieved" segments means the shaft stays straighter and is more stable.
  
  The very nature of wood grain causes solid shafts used by competitors to have more stiffness in one direction than another. All flat laminated shafts are stiffer in the same manner. The OB-2's radial construction provides for consistent stiffness in all directions.
  
  Straighter and more stable shafts play very consistently, which leads to confidence, and confidence helps everyone play better.
  
  Combine this "consistency" with the other benefits of the OB-2 and you have the best "Over All" shaft on the market.  

• Efficient cue ball spin
  
  The unique construction of the OB-2 combined with the long taper makes it easier to apply spin to the cue ball. Being able to spin the cue ball more gives a player confidence.
  
  The unique patent pending construction of the OB-2 allows the use of a longer taper. Long tapers used with solid shafts typically play inconsistently, but with the added stiffness of the OB-2, the long taper gives increased cue ball spin without the loss of control or consistency.
  
  As an added bonus, the increase in spin means less cue ball deflection. The same amount of spin is achieved by hitting closer to the center of the cue ball, which naturally deflects it less.
  
  Combine this "added spin" with the other benefits of the OB-2, and you have the best shaft on the market.   

We all want to win more games. In order to win more games, we must miss less often. Playing with the OB-2 instills a strong feeling of confidence, and this is what is required to make more shots and win more games.

How does it do this? The thing that most players talk about is how good it feels, and how confident they are playing with it. When you play with equipment you trust to help you make more shots and get better position, you are more confident and win more games.
