what length static rope to make tr anchor

Hey! sorry if this has been covered before. I'm climbing an area that most anchor points are trees now. Was wondering what length y'all use? Was going to by 50ft but then I read of people using 100ft. 100 seemed over kill but maybe not.

thanks kevin!

Are you making a quad? with bolts it's typically 15-20ft in length, with trees it's more site specific.

I've had a 50ft for an area that has trees 12-20 feet back and never had an issue. I use tubular webbing to wrap a tree to save in rope material and keep a 20-30 ft static rope just in case.

I have  two pieces of static rope - 60 feet and 80 feet.  I bring the appropriate one for the cliff in question (or both).  Each has two 18" pieces of tubular webbing that I leave permanently on them.  I slide the webbing to the places where the static line goes over the edge of the cliff.

50 feet with knots and such will only allow you to use a tree 20-feet or so back from your edge. It won't allow you to use multiple trees or to wrap a big tree/boulder far from the edge. I rarely set up TR rigs any more but at J-tree, if doing it, I can easily find use for 100 feet of rope sometimes. 

I have 2 100ft static lines, and a climbing friend of mine has a 50. Only on rare occasions have we needed the 100ft, but it has happened.

50'

8" soft

20 m has always worked for me.

Kevin, you're going to get a variety of answers (as you already have). The important thing to note is where and how you will be using this static line. Are you anticipating using the line to connect a few pieces of trad gear together within a few feet of the edge or will you be wrapping natural anchors (trees, boulders, etc.) that require additional length or need access to anchors great distances from the cliff edge? Are you trekking several miles uphill to access the TR anchor locations or a short jaunt down a paved trail where the extra length (and weight) of the rope is tolerable. These are questions you'll have to evaluate on your own, depending on your location and experience level.

I'll add that it's easier to cut a rope shorter than it is to make one longer.

At Peterskill I had a 150ft, which I cut into a 100ft and a 50ft. This works well, as neither is too long and unwieldy and I can work with a variety of rope lengths. Maybe 75% of the time I use only the 50ft, 20% of the time I use only the 100ft, and 5% of the time I use both.

If I had to choose one I'd choose the 100ft: even if you don't use the full length most of the time, the excess rope can be useful for getting down to the anchors. Often, I'll rappel down to the master point using the loose end of the rope, then swap over and rappel down my TR line. This is faster than the walkoff and a lot less sketchy than downclimbing to the master point.

Shameless self promotion here. I’ve got 100’ of 9mm Sterling safety pro that was cut off a 600’ spool for canyoneering. It’s brand new, $50 plus shipping if you are interested.

Anybody want to split this with me? 50/50, as they say.

Have a 65 footer than works most of the time.  Sometimes need to supplement with a cordalette depending on the location and how far back the trees are.  

On the other hand a longer static line could be multi purpose and serve as a dedicated rap line in certain cases. Sometimes at our local ice park we will set and reset multiple TR's and will leave a rap line in place throughout the day.

Exactly what we get taught in SP1 instructor trainning. I run a 100ft 10mm static as well, tie a clove on the extra lenght side and a stopper somewhere just past my master point and gri down to perfect my master point and make the rap change.

 Rather have more rope than i need than less.
