Hopefully this will make your decision easier...
A swing is a non-manipulated motion. This means that the ball weight should swing without you having to control or hold onto it. If the weight is too heavy, you will be prone to manipulate it, which creates injuries and diminishes performance.
Second factor is matching up speed with reaction. Ball speed is a good thing but not if you are throwing it through the break point. But if the weight is too much, then you decelerate which creates unnecessary over reaction and control.
When bowling balls are designed on a CATs system, optimum core to cover distribution is 14lbs.
The last factor is comfort and ease. If it feels better, than use the lighter weight.
Bowling balls pick up speed from the top of the swing through release, comparable to G-Force. Usually 3-4 times. So a 15lb ball becomes a 45-60lb orb. Multiply this through 3 or 4 games.
Anyways, if you a comfortable with the 14lber, go with it. Give it time.
