I didn't make a conscious decision between the Sport Strap or the RS-7... I just bought the RS-7.
Below are some bad photos taken of my setup for safari and sports shots - where mobility is needed. These were taken in a hurry on my P&S, so I don't plan to include them in my modelling portfolio ;-)
If I don't have to move often or swiftly (eg when shooting landscapes rather than lions and leopards / surfers), I'd swap out my monopod for my tripod. The OS on the Sigma 120-300mm lens is very good, but no OS can match being locked down on a tripod for a longer exposure.
This setup does permit the lens to swing whilst walking, but a hand resting lightly on the lens foot takes care of that. It might not be ideal for snow shoeing if you use handpoles for balance.
Thanks for the suggestion Harry. It looks interesting. Unfortunately, the 100-400 is less than 1/2 the weight of the Sigma 120-300 f/2.8, so it may not work (I couldn't find any specs on weight capacity). It's also 4" longer.
Anakha, that sound like an intriguing configuration. You wouldn't have a picture of that by any chance, would you? Also, what prompted you to chose the RS-7 over the Sport Strap? They both seem to be suitable and it is hard for me to tell when you would use one over the other.
I will be doing some snowshoeing, so there would be an advantage to having something that secures the body/lens in the front rather than the side. But like everything else, it may be expecting too much to get a great system for hiking that is also usable for snowshoeing.
Setup for taking photos - Gitzo monopod, Markins Q10 head, RRS Long Lens Support, Sigma 120-300 OS, 5D3, BlackRapid RS7 strap, Optech backup strap
monopod collapsed - not good in a crowd of people, but faster to setup for photos
monopod collapsed and dropped down - better in a crowd of people, but takes longer to set up for a shot
