I have a Dual SpiderPro system i have been using for years. I ditched the belt system and just ran the latches (with a closed loop) on my wilderness riggers belt. a great system that held a pair of 1DX for years, after around 3 years i needed to replace the pins which were worn quite heavily and misshapen. I no longer use it, but only because i no longer work as a photojournalist or own 1D cameras. when i get another SLR I will pull them back out of retirement. takes a bit of practice and getting used to - but i Love the system. I don't like the clip on this version, but thats just me, I don't like clips like that. would likely be perfect for a mirrorless or small DSLR.
