If it don't do something to the dreaded neck diving of basses, I don't think I'll ever spend that dough on any strap. You have to have some threshold of originality or cunning idea of it, to solve problems for real. If not head diving, maybe a material that adds to the density of the body and removes dead spots?

Or being able to hold the bass stilll when doing on stage antics like a "bass swing" around the body?
If one don't bring something new to the recipy, then don't put it out on market. It's just a posh strap. Not that different from any other strap that's posh too.
I would love to and automatically adjusting strap, to sense my body length, and bass guitar body weight, and adjust accordingly. Mechanically without electronics, at that price. Of course I can set that myself manually too, as I always want to keep any bass in a certain position that is comfortable for me. But that's the thing, if I change bass I can use the same strap, and no matter how the other bass is designed, the strap adjusts automatically to my set preferences. Up under the chin, or low slung punk style. Or anything in between. I have yet to see a strap, with a simple function, that it doesn't fall down the back when sitting down and then standing up. It should stay the same place, or adjust accordingly. No matter what level it's set at. I e that when I am standing up it should be low slung, or vice versa.
At that price at at least.
