| | | Talk to some slackliners, this is their favorite subject. What we usually do is run the rope (webbing) across, hitch a biner on it, go around a biner on an anchor, back through the first biner, another biner on the anchor, and then back through the first biner again- beneath the original pass. Works really well with webbing. To get longer stretches more taught we repeat the system off the tail from the above, abusing the f-ck out of mechanical advantage.

| | | just how frayed is your "old frayed" rope? heh small diameter steel cable is pretty cheap, you wouldn't need much to run a camera across; could get away with some super thin diameter stuff.
I've actually used the Petzl Minitraxion for tensioning rope. It's internal progress capture works splendidly. The mini is cheaper than the pro, as well as smaller and more lightweight. Some advice: to unhook the capture spring, you need to pull the rope TIGHTER than what it's currently set at, to release the device. (this is true of most progress capture systems. Once it's jammed up tight, you have to unweight that part to release it) So if you pull it mutherhellafricking tight, and then capture with something mechanical that grabs it RIGHT THERE... hehehehe.... well you see the problem. =) Again, with just the weight of a camera you could probably achieve enough tautness with a simple pulley and prussik. Don't forget that the force at your anchors is largely magnified when you're tensioning a line, and once you weight it laterally, the force at the anchors jumps up by, what is it, a factor of 5?
