I've got a few of the Op-tech boomerang-shaped ones: it started as the easiest way to get into a decent strap for my Mamiya, (that's about the only thing I commonly wear around my neck, not only is this comfy, it makes a handy back-of-the-neck warmer when I'm using the WLF in the cold.
Also good for my F1-N, since I scored a winder. (this camera can get heavy when there's a bigger lens on there.)
The different colors are useful to me, too, for ease of telling them apart. I've about tapped the line out for colors sedate enough for me to stand, though.
I'd say, Lam, that those are about as easy on the back as anything out there, to my knowing. For hauling, you might try a backpack, (I'm not wild about this concept, myself,) or something you can sling courier-style, with the right pad. (I actually used to *be* a bike courier, so I'm set there.
)
For lighter things, I like the old Lowepro Speedster: (you can still find these) it's a little less than an inch and a half wide, no padding, and an extremely grippy rubber-thread weave on one side. Prevents my bridge camera from flying away, and it's nice for everything but really heavy stuff. Takes up like no space in a bag, too, so it's great for second bodies. I wish *those* came in different colors, too. Perfectly comfy for a metal SLR and a prime lens. I might grab another one for my Pentax DSLR if the green Optech I scored is just excessive. (I don't want to take the Speedster I have off the Lumix cause my dear one will be using the little guy here and there, and the stock strap is a stupendous hassle.
It's highly unlikely I'll be carrying both digitals at the same time much, anyway.
Chatter.
Anyway, you might try a Speedster if your rig isn't too massive. Very simple, works great.
(Just in the nick of too late with the advice, it seems. I'd be curious to hear how that thing works out, Ping.
