EDIT: opps, realize i typed '2' twice.
ive been extensively reading up on cotton carrier, spider holster, and black rapid double R. they all have their pros and cons. for all of those that have done weddings/events with 2 cameras, what is the best way to carry them? assuming you're not carrying a bag with you, but if you are, do you prefer to put the 2nd camera in the bag and have 1 out? or have both cameras out and use the bag for lens, flash, and accessories?
the 2 weddings i have done with 2 camera setup, ive had my girlfriend hold the 2nd camera for me, but this time, she wont be around. i dont like using neck straps, so both of my cameras have no straps on them. i have a kata reflex E neck strap in the bag with me at all times if i ever need to sling my camera.
my cameras are 1dm2n and 5dc. they both have the canon e1 hand strap. the 5dc does not have a grip but have a camdapter plus manfrotto on the bottom to utilize the quick release for my tripod and provide a lug for my hand strap.
let me know what do you guys prefer.

Very heavy. But if I had a camera and binoculars, that would be fine.
