Hrm, I use the big boomerangey Op/Techs on anything that might get heavier than a certain amount, ...I was a skeptic about the neoprene, but these are nice. ...Otherwise, my favorites are actually similar to those Domkes, and ...the suede Tamrac types I used to use. If you want a narrow one, that's still padded, that was kind of where I'd go back in the 80's, when mostly you could have something like that, or wide webbing that spread the weight but created its own discomforts for me.
I like the Lowepro Speedster, it's like a Domke gripper, but a bit less than an inch and a half wide, and very grippy. Very good for lighter rigs, anyway, up to, really, an old metal film body with winder and not-too-heavy lens.
I'm wondering if your desire for a narrow strap is kind of for similar reasons to what I had before I tried something new: not really figuring on that the newer designs can be wider without being very uncomfortable. (Though I think Tamrac and Lowepro both have straps which are narrower, with neoprene pads. A friend who tried the latter doesn't much care for it, if all I really know,
So, that's all I can say for that. But... Some folks mentioned some new and neat-looking things on another thread. One was, a Crumpler 'Industry Disgrace?' (points for memorable names, I think that was the one, though.
) And the other was... Something I'll have to look through old threads for. Those might be worth checking out.
Here, I found the one I'd never heard of. *this* looks pretty intriguing, from some mention on another thread:

It's called a 'Pacsafe,' ...looks pretty good. I think I'd bypass the dog-clips on it (don't like to trust that sort of thing) but it's narrow and padded.
