As Rick has ALREADY mentioned....statics weights, i.e. finger weight, is not what is pushing the ball down the lane too far. How far is the pin from your PAP? How much separation is there between the flare rings?
If the pin is too far from your PAP, the core is not creating enough flare or the flare rings are too tight and the ball is rolling over oil for most of the lane, creating too much length.
Surface dictates length first and foremost. Flare allow for more overall 'hook' potential.
