I have been climbing with this system on and off since January. For canopies with a dense crown it works really well. For long limb walks getting back in can pose a problem that can be easily fixed. Before walking out install an additional prussic and revolver on the climbing line, and then feed the tail end of the rope through to act as a mechanical advantage. Simply pull on the tail end to tend your friction hitch as you come back in. I have been using a DMM Heart attack figure 8 with the revolver and had no wear issues. The length of the split tail is critical to ensure it grabs every time. Redirects are a cinch simply belt in and direct the rope F8 in the direction you want to go and re clip in. You can get creative by using a throw line to pull the climbing line into the position you want to go prior to ascending. This I used to good effect on weeping willows.

The main drawback I see with this system is what are the forces being created on the branches as you redirect the climbing line through the tree? This is definitely a system for an advanced climber but has tremendous potential as it evolves.

Looks good Drew, the only thing you may want to include is a requirement for the crew to discuss how a rescue would be performed i.e. SRT or DRT technique, this rules out any confusion should a rescue be required. We have taken this one step further and have an in house document that describes the various climbing and climbing /rescue techniques know as our " climbing policy and procedure document " Which we require every climber to sign off on. Should an accident occur this document provides Workers Compensation with detailed documentation that every worker has received proper training and understands the companies policy This shows due diligence on behalf of the company owners. This may sound like a bunch of bureaucracy but Worker Comp is all about documentation

Hope this helps;

Hi Rob Murph:

I really like the look of this system but how do you put the chest harness together and prevent the mini triaxion from bunching under your chin? A chest roller has a fixed plate to pevent this but costs $120 plus dollars and has to remain in place as you climb or be removed and lowered to the ground.

Thanks ;
