I would recommend the SOP, I have used it for the last couple of years and love it. It's comfortable, weighs very little, and easy to use. WhatI like best is thatI can put it undermy jacket so you don't even know you're wearing it. I have no experience with the Fall Guy vest, but I looked at some of those vests when I was buying a harness for my dad and I found the vests that I was looking at to be too heavy and made with metal buckles. I thought metal buckles would have the chance of causing noise at the worst time (banging against my weapon or rails on the tree stand). I have not had a problem putting the harness on, sure it takes a couple of minutes but it takes time to drive to the hunting area, walk to the tree stand, climb the tree... you have tobudget the time for everything.
