Hanging a heavy camera from my neck is uncomfortable. Slinging a camera or camera bag cross body seems the best way to go. There's no weight on the neck, no need for melon-sized deltoids or epaulets to keep the strap in place. During my initial research, the Internet kept tossing up ideas for camera straps of various sorts made of braided parachute cord.
Then it occurred to me: why not simply extend the factory camera strap with a bit of parachute cord? It would sling cross-body and slide, but not too easily, and it wouldn't have any metal that could make noise or potentially bump into the camera body.
So here is the result (yes, I realize that is not a Pentax below, but I tried it for my K-5 IIs, and it works just fine, even with the 55-300 attached):
It stays in place but it slides when needed. It doesn't rotate, so the camera stays in the same orientation.
Nobody is going to approach you on the street and ask, "Where did you get that beautiful camera strap?" (So your carefully prepared story -- these straps are made by direct descendants of Norgay Tenzing above 15,000 feet in Tibet -- will have to wait for another day.)
If you find the ragged ends of the parachute cord distressing, you can up your game by melting the terminus of the cord, like so (do this outside and don't breath in the fumes):
Of course, at Classless Camera Research Laboratories, we charge extra for that.
Cheers, Jock
PS A hank (about 18 feet) of parachute cord can be had in various colors at a big box store for about $2US.
