Don't put in concrete what is not made for concrete. I'm not even fond of the wire mesh made for concrete. I would use rebar all the way. As Ddawg stated it is made to hold it from pulling. Rebar is also made to keep one side of a slab from dropping lower than the other side if (better yet when) you get a crack, and preventing a trip hazard. Chain link fence would stretch every which way. Also make sure your base is properly done. If it is stone, make sure it is tamped down, tamped some more, then tamp again for good measure. If the kids say they are bored, let them tamp some stone. LOL!!! If stone is just dumped and spread around, you can place a bet that the concrete will crack later on from the stone settling.
