I'm a happy Cotton Carrier user. I used to struggle to transport 2 bodies, my FA*300/2.8, FA* 300/4.5, a reasonably large CF tripod with ball head and Wimberley Sidekick, various TCs and other accessories, a macro lens, and a wide to normal lens, and a tiny fold up stool. Shooting birds and other small critters opportunistically, both cameras had to be available reasonably quickly, and I generally have to walk between 1/2 and 2 miles to get to some prime shooting spots. Comfort and convenience/speed are priorities for me over style (I also use photo vests, so looking geeky is something that doesn't bother me).
With the K20 + FA*300/2.8 (with hood mounted) on the chest unit, and K-7 +FA*300/4.5 (also w/hood in shooting position) on the holster carrier, the Cotton Carrier is easily the best carrying system that I can imagine for lenses like these. At first, I was a little doubtful, but after using this system for a month, I'm a believer. It's a very high quality product throughout, and there is no more comfortable and convenient way for me to carry the bulk and weight of my normal gear while keeping the cameras ready to use at a moment's notice.
It's admittedly pricey, but when I considered that I normally carry over $6K worth of bodies and lenses, this became much less of a restraint. I was a little concerned with the security of the hold when I first got the CC, but I'm 100% confident of my gear's safety at this point. Depending on the angle that you mount the adapter, it takes up to a 90° rotation of the body to release it, and even if the camera did turn this much, it's weight would still keep the adapter deep enough in the holder slot that it wouldn't be able to fully release and fall. I also use Camdapter grip straps, so grabbing either camera with just one hand is still a secure operation.
I also found that by reducing the stress and effort of carrying the gear, I was able to settle down much more quickly, and was physically more capable of properly executing the shots I needed to take.
I don't think I could be more enthusiastic about this product.
