Had a couple of opportunities recently to try out the new Tree runner rigging bollard I picked up for CTC's lightweight rigging kit from the APF
Rigged down this smallish sycamore last week
Nothing overly massive or complicated but still needed rigging
The ratchet holds the bollard well, and there was no sign of any movement, even when rigging some pretty hefty lumps (kind of size lumps that need cutting into 3 - 4 pieces in order to lift them onto the van)
We were using it with a 16mm rope, which is technically bigger than recommended (14mm) but seemed fine, just needed less wraps than you'd need with a thinner rope.
As a secondary device for reductions/limb removals it would more than sufficient and a definite improvement on a portawrap or similar. The main advantage being the user friendly nature and how quickly in-experienced ground staff can pick it up and get to grips with it.
Being rated at only 500kg it is no replacement for a Stein bollard, but would be a good device for small crews and start ups. or as a secondary device for larger firms.
