Too late! I have already done my first work job using the RRP...first time up the rope was to get into a maple to limbwalk to take limbs off the gutter encroachment. It worked a treat. Only problem was getting the chest biner unlatched once I reached working height. I did bounce test it several times and went up about 5 feet and descended a few times to be sure I could actually get back down.
Years back when I switched from a Distel (?) to an eye-eye knut (?) I used two hitches at the same time ....kinda what I think Kevin is suggesting. Top hitch was primary and black was the test hitch. Kevin has to be careful that he will have a lot of people with varying degrees of skill and common sense using his product. Suggesting two ropes is probably partly CYA, I suspect.
Here is how I did it then...as I learned to trust my new setup...I was also testing some hitch cord that was not specifically designed for tree work.
