Trey Ratcliff posted this on his G+ feed so went to take a look and after checking out that they would mount onto my RRS L plate, I backed for a Slide+Clutch combo.

They have a couple of good videos on the site demonstrating the two different items. From my POV it costs over $100 NZD to get a Black Rapid and I never bought one cos it never felt like it fitted or sat properly.
Currently I use a wrist strap for walking around type stuff so like the idea of the Clutch quite a lot and the price for the two of them is about the same as the Black Rapid. If it doesn’t work out for me, fairly sure I could find a good home for them elsewhere.
Love that you can mount both and that they are easy to attach and remove, and it looks like they should ship in a couple of months so instant gratification 🙂
