they probably are....just a hunch, but the scratch might have more of a 'dampener' underneath the binding to absorb shock from jumps and such. I just mounted a pair of powers tonight....the dampener rubber piece thingy was pretty slim and only on the heel...this may not be the case for the scratch binding.
im just gonna sling crystal meth so i dont have to get a real job and can afford to ski, with the way my senior year is goin though thats probably one of my few options
who cares about lighter, like 10% is going to make a difference. I have the scratches, and like them, but they are starting to fall apart, and i got them last christmas, so about a year.
