Actually it adjusts so much easier the wrong way, I tried it, I loved it! The way the straps work with the adjuster, it's just such a major pain to buckle them in. I love having the knobs on the side though, as opposed to in front. Much easier for RFing. But when worn properly that thing is just more of a pain than other seats. Why does it have two straps anyway?
It looks safer because it seems like there's more side protection. There's one strap over the shoulders, one under the armpits across the upper rib cage, then one over the upper thigh and the crotch strap. So it looks like you have three straps around the body holding it in. The correct way only has two, the shoulder and the upper thigh. KWIM? I can get a pic of the two different ways to show, for those who can't visualize it or don't have a Triumph.
I did not tighten these enough, just enough to keep them in place for pics
