Default Difference between Align 425F and 425D??

Does anybody know the difference between the Align 425F and 425D blades? They look the same and all of the specifications listed on Align's website are the same. The price is different and they took the time to make different boxes so I assume something has to be different

Looking at both pictures I noticed one set has one rod running through it and the other has two rods. What that means, I don't know.

1st, the rods are actualy weights,
however, altough there are two weights, the overall weight seems to be the same (120 grams).
so my guessing is that the diff, is the CG of the blade.
i.e. the CG is more to the ends of the blades.

ohh, and another thing - the F are blue .

now, have look at http://helifreak.com/showthread.php?t=87675
