If we are taliking about plastic zip ties, I think they are probably most useful for lashing purposes, such as for constructing a shelter of some sort, or a bed support to get one up of the ground, or any other number of uses that you may use cord for. They are much faster than cord in these applications, and one doesn't need knot tying skills. I'm sure one could come up with numorous uses for them, you just have to decide if they are worth it from a weight/space vs. usefulness perspective, which is of course different for each individual.<br><br>Regards,<br><br>Greg
