ascending with tibloc or prusik

I am planning to do some photography work with some friends leading sport routes. I am thinking about setting up a top rope next to the route and ascending up and down with either two tiblocs or two prusiks. I know one of them will be connected to my harness and one for my foot. My question is will I need to have another way of connecting myself to the rope other than the tiblocs/prusiks? I was thinking about running my grigri between the two ascenders for added safety. Does this sound like a good idea or are there better ways of doing it? Or are the two points connected to the rope (tibloc/prusik) sufficient and safe.

Thanks
cody

The most common approach is to attach an ascender (or prussic/tibloc) to your harness, and then hang an aider (or sling) from the ascender, and then run the rope through a gri-gri. You stand up on the aider, pull in slack on the grigri, and sit down on the grigri. Then you slide the ascender up, stand up on it again, pull in slack on the grigri, etc.

It's isn't essential to have a second ascender and aider, but if you're jugging a lot, then it is faster.

Two connections to the rope if using ascenders, one is good if using the Grigri.

I'd go with the Grigri on your harness and use the Tibloc with a long sling for your foot ascender.

Prusiks would suck mightily.

The one connected to your foot should ultimately be connected to your harness too, if that wasn't already obvious.

Beyond that, a Google search of "ascending rope" or similar terms will get you lots of posts, pages, and videos of exactly what you want to do. Simply wade through through the information until you find a technique that matches your desired gear and safety factor.

I forgot to mention that using a GRIGRI as part of your system should allow you an easy way to move down the rope as well as up it. My opinion is that a GRIGRI and a Prusick might be a good combination since you can relesase the friction knot while ascending. Releasing a tibloc would not be as easy. I have not tried this myself.

If I were setting up for a TR Photo shoot, there are three things that I would bring, a Pinot Gri with ice,or a nice Pinot Noir, or maybe a great single malt Scotch but that would depend on the weather.

After that I would bring a Bunsuns seat whether home made or purchased, a asscender, a gri-gri a pmp pulley and a rope a few lockers and some slings/runners/cordage.

Set you're TR up, toss the rope, hook up the gri-gri and rap, for asscending add one Jummar(jug) and a one pmp pulley, and one Etrier, follow the proper set up and jug away, for the shoot sit down(bunsuns chair) and take the pic's, for detailed info head over to Chockstone.org and look up Jummaring with a gri-gri/ asscending.

The Grigri is not designed to be an unassisted break and though I know many people use the Grigri in hands free situations, I would personally recommend you invest in an I.D. This is the commercial version of the Grigri which has a brake built in. Its designed to be used hands free which is ideal if you are hanging on it for things such as photography.
For ultimate safety I would be inclined to drop two top ropes, one to ascend and the other with an A.S.A.P on it. The reasons for the second rope and the A.S.A.P is because if you take a fall on an Ascender or Tiblock, you can shred the rope.

For years, i've used a grigri, ropeman with slings, and a soloist. Steve

For ultimate safety you should just stay on he ground, because ass-ending is just plain dangerous!

I'd also recommend investing in a device that has a "brake" built in as opposed to a "break" - but I guess it depends on what you are hoping to accomplish....

Thanks boys. As English isn't my first language I'm grateful we have some pedants in the house. If you ever come to the French alps I will be equally happy to help you out with French Tongue
Its just a shame that what i said, which was good info, was lost by my language not being understood. Unsure
I think its time I gave these forums up.

We are sorry, don't go. We REALLY could use more intelligent input around here.

But to the O.P. gri-gri + accender/ prussik is GREAT, but whatever method you use, see also "tying in short". Boatswain (said bo-s'n)seats are great for long sittings. You can make your own super cheap & easy, and I would recommend it be hung from a separate line.

Or you can tie backup knots- it's a whole lot cheaper and easy and works well.

Backup knots are essential. There was a recent death and a big grounder recently as I recall, both without them.

As mentioned above a standard system is with an ascender for the footloop and a Grigri on the harness. The ascender is connected to the harness with an additional sling as a backup and makes knots superflous.
