I own both PD Slide and BlackRapid straps I just want to share some experiences I had with using both straps. For years I've used the orginal BR RS-7, mine still says Patent Pending haha but I have officially retired that strap since it was worn out, but it has never failed me. I have a newer one, a slimmer version which I do not like but still comfortable and functions the same, just better quality connectors. But I wanted to try something different and did some research and bought the Peak Design Slide because I really liked the idea. It's a really versatile strap because you could use it 3 different ways, a sling, neck and shoulder strap. I also like how it comes with a arca-swiss compatible quick replace plate where you can connect the little anchors to, it made it a breeze to put on a tripod and remove the strap to prevent camera shake when doing long exposures. I also really liked fact that it was connected to a strap lug and the tripod plate and not JUST the tripod socket, all these felt really secure connections and I was quite confident in it. Another thing I liked when its connected in the way I mentioned above (strap lug and tripod socket) the camera sat stable at the side and not flopping around like the BlackRapid straps. Now what I don't like about the Peak Design Slide is that its a little big, looks a seatbelt and the ends where you slide and lock the anchors to are kind of bulky and I find them often to be in the way and I have fumble a little bit to access the buttons on the left side of the camera. It's not a super big deal, just something I found to be annoying. Also when you remove the strap, you have a bunch of little anchor things hanging off from your camera, making noise and getting caught in things (yes, I have had them get caught in things). The biggest issue I have with the Slide is that it useless if you are wearing a backpack, messenger bag or whatever, it does not slide well because it gets hung up on your bag's strap. So after using the Slide since last summer I decided to remove it from my camera and start using the BlackRapid strap again to see what I was missing and I started to remember why I liked BR straps. For one thing, there are no silly anchors hanging off from the camera so when I remove the BlackRapid strap along with the Fastenr, there is nothing attached to the camera making noise or getting caught in things. I can shoot strap free without being annoyed by them. The second thing is I feel less restricted when shooting, I can shoot vertical without the strap being in the way or interfering when adjusting settings, almost as if I am using no strap. The third and most important thing is that I can wear a backpack or a messenger bag and have them not interfere with the use of the BR strap. With that being said, I think I am going back to using the BlackRapid straps because they just make more sense to me. Yeah, I'll have to deal with the camera flopping around again but honestly, when I have my camera it's in my hands 90% of the time anyways. It's not a huge deal I made it out to be. I know some are worried that having your expensive camera connected only to the tripod socket could come loose and end up breaking your camera. But I've used BR straps for years and I never had one come loose. They have always remained tight and secure. Of course, it helps if you periodically check to make sure it's tight. I'm also not sure what some of these people are doing with their cameras that causes these incidents. I really like Peak Design and I think they make great products but sometimes one thing is just not for everyone and when it comes to camera straps, I think you have to find something you'll be comfortable with.
