Redline,
Not trying to discourage you or anything, but the angular one has a mass bias rating higher that your other balls mentioned here ( big time pearl and xcel pearl).
I have had the same problem with assymetricals that have the mass bias in the strong position.
I have an original inferno, and after hearing MUCH hype, bought a classic zone. Drilled it pin over bridge, mass bias strong, and it rolled like aTURD!
I have medium speed ( 14-16 mph ) and plenty of hand. What was happening to me was that the mass bias was getting the ball to turn over way too early, while it was still in the head oil. Because of the heavy oil, it would flare a bunch, but not hook. By the time it got to the breakpoint, it didn't have much flare potential left in it. It would roll almost out and hit like my little sister, not much at all.
You may have the mass bias in a position that is too strong too early for your hand release. As long as you play a straighter line, it works fine because it doesn't have to expend lots of energy "turning the corner", so to speak, but when you play a swing shot, it burns all the energy before it can get out and back. I first though it was the lanes, but like you, all my other stuff still worked and worked fine. Only the classic zone had this problem.
Since then, I have learned that, for me at least, I have to be very careful where I place my mass bias on balls with a strongish mass bias rating, lest they befall the same fate.
