Searching for a Strap

I'm not familiar with the straps you mention, but a while ago, I purchased a couple Leica straps on eBay. I had an R7 some time ago and really, really liked that strap, so they're all I've used, even for larger set ups like the Nikon D200 with extra grip and large zoom.

They are very simple, thin straps with a small rubber pad for your shoulder / neck. I like them, because they are descreet and easy to wrap around your hand for use off off the body. I can use diagonally as well.

This appears to be the one, though I picked them up used:
