I had a serendipitous eureka moment last night on this very thread, long after my previous post here. I trotted out my Daion Savage fretted bass. For many moons I have tried to get the lower strap end to settle over the forearm carve of any of my FSOs, partly to increase the playing angle of the bass as in the first Bunny Brunel pic in post #28 (straight wrists), but mostly to pull the bass body more snugly against my body to reduce the pull of the bass on my left shoulder. It's a fight to get the strap in that position, and once there it's a fight to get it to stay there.
So last night I got to goofing around with this guy (stock photo), which had on it one of the much-maligned nylon straps, let out almost to maximum length.
Be doggoned if the back end of the strap did not default right over the forearm carve and sort of snug itself beneath the back of the bridge (sort of like an anchor). I think this sort of "automatic" positioning is due to that cut-out at the butt of the body; the angle gets changed. Anyway, this allowed me to tilt the bass up more. I could not get it up to sixty degrees, but it settled in quite nicely at forty-five with no neck dive and allowing me to play with both wrists straight.
But the big payoff was that the bass was drawn back against my thorax, which bore a good bit of the load and made the perceived weight of the bass noticeably lighter. Much more comfortable, and that heavy bridge became less ominous. If I can figure a way to pull the top strap end closer to my body I should really have something: an eight-pound plus bass that feels like it weighs much less. And mind you, this was with a stinko nylon strap.
Another surprise. I can position the strap far out on my left shoulder, on that corner where the clavichord ends and as far as possible from that tender area of the shoulder area adjacent my neck. Shoved the strap out as far on my sweat-shirted shoulder as I could, and the darn thing held position. No dropping off the shoulder.
If there is a negative to all this I have not found it. I'm going to investigate further. This post is just an FYI.
