If you have shoddy ground workers cutting near the base-tie, you should be concerned. If you're dropping chunks that could fall against the base-tie and severe the rope (particularly if tensioned), it might be time to go to a canopy anchor. I am certain that if there is risk of damage to the base-tie, that my lanyard is full life support strength, including a possibly shockload from loss of support by the climb-line. Someone you Trust to watch that potential safety situation closely, can help to monitor the integrity of your base-tie.
Canopy anchors don't spread forces as much, or have as much rope in the system for shock absorption, nor do they have emergency lower-ability from the ground.
Trade-offs.
Pull test your canopy retrieval system either from the tree, or with help from the ground worker by unweighting the climbing rope and simulate removal. Save a re-climb.
As I mentioned, you can have a safe canopy anchor that isn't cinched as tightly as it might be absolutely possible.
I climb a lot of Doug-fir. If my Running bowline is 6-7' in circumference, angled downward, it will be waaaaay easier to retrieve than if it was as tight as possible, cinched in a horizontal loop.
I will need to get a picture later to better show what I mean.
Figure out which is better for each situation. Its very variable.
A choked canopy anchor is totally omni-directional. A redirect may not be. In my case, cedar branches droop. Its very possible to have the rope slide down the limb if loaded in the wrong way. Be aware of the actual situation, rather than guidelines or trends.
