I need to learn more about strap/carry options for the D7100 now that I have real carry lugs on my camera body.
I love the BR Wrist Strap. I've carried my D7100 (with battery grip) with a Sigma 50-150mm f/2.8 (about 3 Lbs all by itself) on all-day shoots pretty comfortably. I used to use a sling strap 99% of the time but it's been replaced by the wrist strap. Mainly because I don't like bulky stuff. It's why I use a BosStrap sling-strap vs. any of the BR sling-straps; where the BR straps are thick and stiff and almost over-engineered (just my opinion) the BosStrap is light and flexible. The BR wrist strap is even more minimalistic, and that's why I love it. At first I thought I'd miss not having both hands free, as I do when I'm using a sling, but it turns out I prefer having the camera in my hand as I carry. I still have my sling, and still use it, but the wrist strap is the new daily-carry solution.
If you have really big hands, you may not like it. I have larger than average paws and I can make it work fine, but for those with real "catchers mitts" this may not be the case. I also wish the branding was a little less billboard like.
