I've tried looking this up, and I get no real answers when googling. Anyhow, I accidently saw a video on the Hensley Arrow last night. It was explaining something else, but it was talking about the spring arms as the 'handles' on a wheelbarrow, and your arms as the 'chains' that lift the spring arms. They were talking about changing the angle of the receiver to match the stinger. However, if I were to put that to practical use, does that mean the back legs of the wheelbarrow would be like the back axel of my truck, and when my arms lift the legs up they are taking the weight off the legs of the wheelbarrow? Also, I suppose that would make me the TT and it would, by lifting, put part of the weight back on me? Am I on the right track here, or am I just crazy?
