Doc, if you want a more even reaction, then bringing the ball back to zero(ending CG at the perfect center) weights will achieve your goal.
If the ending Cg in the side, finger and top weight quadrant, it will usually add length and/or flip to your ball. How much they add is debatable, but it is added.
If the ending Cg is in the negative side, thumb and bottom quadrant, it will usually promote an earlier roll with a smoother backend reaction.
The ending Cg, or static weights if you will, has an affect on the reaction, just like the core. Weight is weight, so you should treat it as such. By taking the ball back to zero, you're eliminating the effect of the ending Cg and just relying on the core shape and core angle.
Like I said earlier, the ending Cg (static weights), do affect ball motion. I feel they play an important part in your ball reaction. Others may not. =:^D
