Kryptonium or Magnesium Chassis?

If i'm able to acquire one, would it be better to have a kryptonium chassis on my APRXs? Or is the magnesium one just as light?

The weight difference is very minor between the two, I'd challenge anyone to be able to tell the few grams difference when the boots are on your feet eg the weight of the apxr and apx2r is the same. If you sweat heavily then the kryptonium chassis may suit you better as I have seen the magnesium chassis react to sweat around the mounting holes and eventually delaminate and break apart. Other than that I think it's more a case if you think it will be money well spent...
