Recommendations please

I have just ordered another batch of feeders,to replace my latest stolen ones and would like to know some ideal cable etc,to tie my feeders onto my bird station hooks with. I was using tiny electrical ties for a while,but they were a bit of a chew to remove,although I wish I'd put up with it now. Just need something that makes it fairly easy for me,but probably too much of a chew for the thieves to remove. Btw,I am getting a security PIR light installed next week.
