I use a twelve foot tether while climbing with XOPHC and add a foot loop on a prussic below my rock harness attachment point. When I have to step off the XOPHC, I put one foot in the loop. It allows me to drop down enough to adjust the belt on the hand climber and step back up onto the platform. Same principle will work on limbs and knots. I have to adjust for tree taper several times on way up and down many of the trees I hunt from, being able to leave the platform is the best way to fix the problem. Most frustrating situation is to hang the strap under a bark plate in the dark and can not see the situation, then you have to leave the platform and feel for the problem fix it and then climb back on the platform.
