I own both a BK2 and BK3 and have been using the BK3 for the last 3 weeks. IMO, the BK3 does not have as much ridgidness as the 2 so I am assuming the carbon fiber does well with absorbing the hit. I have tried it with no weight bolt in it and also loading it up with weight (which is not much b/c you cannot fit two of the 2.0 ounce weights in it, no room for the bumper to screw back on). I found that it hit the best for me with the weight adjusted to around 19 ounces. It does blast the rack open nicely at any rate. I have the pleasure of owning a Mezz Power Break Pro also and I feel the Mezz is a little bit better. Unfortunately, for the $200+ more that the Mezz costs, the BK3 is a better deal. Overall, I won't be selling the BK2 anytime soon b/c the 3 has not shown me enough to render it irrelevant. If Predator is listening, I will gladly change this feedback if they want to sponsor a mediocre player and hook him up with a couple cues!!
