Thanks for the replies!

@John - Good to hear it dosn't interfere with another pack. It would really reduce its value to me if this was not possible.... I do currently use the Manfrotto RC2 system. I also read your post on using the arca-swiss system with the BR straps, but I'm not quite ready to switch to arca-swiss yet (maybe when I get some longer lenses with tripod attachments...) but it's good to hear I have options when I do make the switch.

@Rich - I'm not sure that I would wear the strap over my right shoulder anyway, but I'm a southpaw so sometimes I do things backwards.... The clik elite chest carrier seems similar to the lowepro toploader bag I have. The lowepro is primarily designed to sling over a shoulder, but mine came with a harness so it could be worn on the chest (the clik elite may be a better / more comfortable fit though, since it is designed for this from the ground-up). I agree that this provides better protection and still gives good camera access. However at this point I'm looking for something that keeps my camera out-and-ready all the time when hiking, walking, etc. As for skiing, this is more a secondary use. I'm not sure I would ski with it on all the time, but for short periods when I'm taking shots of something in particular (ie my wife or chasing some wildlife, etc.) In this instance I would just want the camera to stay mostly out of the way and (hopefully not bounce around too much) but still accessible. Since you have both the RS-5 and Sport, which do you find better? Are there many differences between them?

On another note, I also like the think tank backpack connection kit, but for a different reason: it looks like it could work with a larger backpack. I'm thinking it might work with my larger backpack for overnight or multi-night backpacking trips. I may have to look into this for the future....

@thekingb - Thanks for the further info. I would have thought also that the BR strap would be better under the backpack as you wear it, but I guess it could depend on the specific backpack and what each person finds more comfortable.
