drilled and slotted rotors

[R Haug <haugchiro@moscow.com>]

List,
I am considering replacing my standard rotors with the drilled and
slotted rotors for my 67.5.
Has anyone used these on the street?
If so, is there much difference in braking with these as compared to to
standard rotors?
Is there any increased or decreased noise?
I would think there may be an improvement in fade resistance.
Maybe a slight decrease in unsprung weight.
Anything else?
Bob
