Synthetic systems while having some advantages, also have some serious flaws. The two that concern me the most are:
1. The main reason (not only) I use cables is to protect people and property. I do not want to put anything in a tree that can easily fail and put the people and property I am being paid to protect at risk. In our area, grey squirrels will gnaw through synthetics.
2. To get the benefit from synthetics, the systems need to be inspected and adjusted. If they are not adjusted, they will girdle the tree. This sets up a potential liability for the arborist. It is a problem waiting to happen. It is the same reason I do not like gutters on my house. If you are not constantly looking after them, they clog up and set up a decay hazard to the house. The "default" setting if you do not do something there is a problem.
