For those of you that do harness work, I have a question about line construction... the following pictures show 2 different examples of made up lines for a single pony. Which one is safest/ most correct? The pair I made up is the wider of the 2, however, I have made up lines in the other manner. I do not use snaps or Conway buckles. Thoughts, suggestions? I'm questioning myself because of a person's opinion and my end goal is improvement and safety is paramount!
