                Static 
                  Systems (Steel 
                  cable & eye bolts drilled into tree) 
                The 
                  Pros:  
                
                  - Static 
                    Cabling has a proven track record 
 
                  - Materials 
                    last longer
 
                  - Can 
                    support larger limbs
 
                 
                The 
                  Cons: 
                
                  - Requires 
                    drilling into the tree, which causes wounding
 
                  - Requires 
                    special tools
 
                  - Static 
                    systems are rigid, meaning the tree cannot move on its own, 
                    sometimes making weak branch attachments even weaker
