I already had a mishap shooting my Canon 5d MII tethered....I broke my circuit board because of the stress that a USB cable causes the camera. I wish Canon went with their 1ds route and made a positive locking device, but alas they have not. So the best alternative I could find was a left-angle cable that will reduce the stress and make it quite easy to gaffers tape to my vertical grip for some added safety. Check them all out here, I just purchased the "15' Left Angle" will let you know how it goes and add some photos shortly. (I am also including the "40' Signal Repeater" that I am going to try out.)
