One day while practicing in my yard, at only a few feet off the ground, I was tethered and I decided I wanted re-adjust the Predator platform. I adjusted the Ropeman down the tether and stepped onto one of my bolts. My body was in a slightly unusual position...almost completely straight at my waist, no bend or articulation. If anything, I was actually ached backward at the waist. I did have the impression that the sling felt like it could possibly slide up on me in that position. That was during the prototype stage of the Recon when we were flip-flopping as to whether it needed leg straps or not (the Anderson never used leg straps with no issues). I discussed that with Mark. I don't single stick or rappel so I couldn't give Mark input those techniques. At that point, he decided to include the leg straps. I'm still not sure they are needed, but they are there if a guy wants them.You don't think it could help in some unforeseen SHTF fall incident while you are climbing, mess up, and take a 1 or 2 foot fall onto your tether in some awkward position? (I always use tether and lineman's belt while climbing, but climb in the dark and when raining/snowing)
I'm really used to a rock climbing harness and the sense of the leg straps keeping you in the thing. I suppose I could climb with the leg straps and then adjust or unclip once sitting at height.
