You still carry chains with your 4x4, right? And now a few lap links and
some pliers so you can quickly fix your chains.

A pair of large link chains along with a shovel
will get you out of places that 4x4 would be stuck without em.

Cable chains are nice for the highway when it is super icy, even
with 4x4 cause they will stop you quicker, but for deep snow, mud
and sand, link chains will really dig you out.
