Think about hanging in the air for any length of time. Would you rather have your body weight supported by your pelvic area or by your waist? The space between the top of your pelvis and the bottom of your rib cage is not designed to support your body weight under stress. It's simple physics.
I know what you say to be true, but, if the harness spreads over the lower (pelvis) and upper part (bottom of rib cage) then thats great, not all waist harness's do this, but some do, so you get the support and the freedom.
I have been pulled quite violently at times, at the time stated I had been wearing the nitrous shorts, so not strictly a seat harness but with a low hook, and this has pulled pretty dead centre on my body, nearly folding me in half where my feet have nearly touched the back of my head!
Moving the hook upwards, the pull can still be the same but the load is moved up the body, so if you have the right harness its damage limitation.
So me, moving from a shorts harness to a waist was a big improvement. Like everyone says’ it’s a personal thing, definitely don’t buy without trying. I got the shorts harness on-line, I got the waist harness in a shop after trying on loads, the guys in S2AS were very patient with me, and steered me away from harness’s know to be a little hard on the body, big thanks to Alex in Hythe
