Foot placement in the loop makes a difference for me. If I get my foot too far in it can get a little uncomfortable if you stay in the loop for a bit.Ok after 4 more hunts in the marsh using 2TC I’m reversing my answer once again back to my original take. 1 inch webbing is plenty for 2TC with rubber boots. I don’t know what I was whining about last week but I have had no problem with the exact same set up recently. I do think the other method of 2TC I was trying last week had me standing in the footloop longer and caused the discomfort. If you’re ascending with any sort of regular pace you won’t be on your footloop long. 1” webbing is sufficient. FINAL ANSWER.
