Let me first state that I did take the two-day workshop a couple of years ago, but i'd like some advice on wearing the vest. Everything I read states that the vest should be snug around the hips so the weight is taken down through the operators legs. I've been wearing mine a bit higher around my waist. Not entirely around my waiste, but more so than my hips. I find if I wear the vest around my hips, I don't have enough clearance for my legs. It's not bad on a level surface, but completely useless for stairs.
The reason I'm asking is it feels like my back is "compressing". I'd like to add additional weight to the sled, but my back tires very quickly. I'm thinking either the vest is too tight, or the spar is in the wrong position. Should the vest be more snug around the hips or shoulders?
