Dynamic cables in the canopy, done lots of cobra and just tried the yale type.
Unsure about it yet, i think cobra is better but the other is much cheaper.
Steel for Rod bracing at union when needed as well but maybe only 1 in 20 Cabled trees i do get that as well. Usually smaller less hazardous trees, more about preserving structure that averting a hazard.
Anyone else run cobra off a central ring system before? We did. I know cobra suggest bracing from stem to stem to stem to stem but... its done with steel so why not.
