Thanks for the affirmation. I got some of the Sterling 6mm accessory cord on order. Last night I watched three online videos of tying a Double Fishermans knot, to make the cord into a loop, then reviewed the Klemheist. I think to begin, I will slide the existing prusik down to the knot end of my linemans and get used to the new Klemheist. I also got a rope tender and that should also help with one handed linemans adjustment while on the tree.
Next questions.....How long do I cut the 6mm accessory cord to have enough for the Double Fishermans and the Klemheist, withoug leaving too long of a "tail" or tag end? For reference, the Vapor Line 6mm currently on my Latitude tether has 5" and that seems quite workable. Also, do you wrap your Double Fishermans? The factory one on my tether has a semi-clear plastic coating.....probably a heat shrink material.
