Yeah, your scale sucks. Is this on a flat hard surface and did you make sure to tear it? Grab a $1 bill and that should be exactly 1 gram. All of this is just what I remember from a 500g scale with small gram weights though, so I just checked my 189 LL2s on a kitchen scale-
if you need to check if this is right- 170 WLs came out at 7lbs, Tyrolia Peak 15s+standard 97mm brakes= 5lbs. I know the true weight of Peak 15s is 5.1lbs, so this scale is probably just a tad off.
That being said, one LL2 weighed 4 5/8lbs, so a pair should be no more than 9.3lbs. Luckily(being sarcastic), the other LL2 in my pair is messed up. It has less tip rocker than it should(like 6mm less tip rise than it should, and starts later) and a bit more tail rocker(longer than it should be, and about 3mm too much). The core taper is also messed up, and it is noticably stiffer than it should be with a less smooth flex(the one done correctly has a bit of a flex point near where the tip and tail rocker start, this one does not), and is heavier(over 2 ounces heavier than the other one, mostly added to the tip and tail which is extra swing weight..). Surface said they will replace it if there is a problem though, so at least I have that to get rid of some of my paranoidness.
on a happy note, the HUSKIES JUST BEAT USC!!!!!!
Strange that your 179s came out the same as 189s did for me. You should weigh each ski and see if they are both the same weight.
Oh and on length, I think that my 189s are more like 187.5-188 along the base.
Sort of, but that's not going to be exact. Things to think about is your taking away 10cm of pretty much the middle of the ski, but things like a wrap around edge on the tip and tail are going to weigh the same no matter what length the ski is, etc. Maby take off .4lbs max. I bet 179s exact weight is a tad under 9lbs.
