How much work is involved in cutting the disc lock off vs. the cable? Would seem to me the disk lock is fast and easy to apply with the same level of security.
The cable around a tree etc. would stop them from picking it up with a tow truck or whatever and hauling it away. Then again if they want it so bad to bring a tow truck they probably have heard of bolt cutters too.
I would go with the disc lock if I was going that way.
