I agree with the fruit being a non-incentive. The calories are built in to the system, but it's too easy to get "too much of a good thing." After 2 servings I count it, personally.
There's debate as to whether white or brown is better for you. I don't think you're looking to go into that here, but just to let you know the debate exists. I used to choose brown pretty adamantly but now I don't sweat it when it's not available.
The behavior WW is driving with PP is higher fiber, higher protein, lower carb, lower fat, they're pretty open about that in their program. It's a little disappointing to see the formula get complex enough to nix the slider, this rat misses being able to easily tweak servings to round up/round down points. =)
