I made a minor modification to my tricams. Since the nylon stems/slings are so floppy, I cut two long, narrow rectangles of plastic from the side of a 2L pop bottle and taped them to the tricam sling on either side, thus giving it a bit more rigidity. I've found this gives me more control when making placements, and I was careful to leave enough of the sling exposed up by the head so that the tricam doesn't touch the plastic when it's folded back on itself or interfere with the action at all.
Is there any reason this is a bad idea or even unsafe somehow?
cheers
