I have this krypto disk lock and the kryptonite chain sold with it (as well as other locks) and although it seems well made, I think it is vulnerable, like many of the less secure d-locks, to being hand cropped - fundamentally the shackle is exposed. However, if it was fully packed, a big set of croppers would have a problem getting enough grip/surface area; hence, IMO how it is used is important.
However, if I wanted to use non lasso type chain my preference would be to use a shutter type lock, rather than a disk lock, where there is no exposed shackle.
