The preferred rope for the friction knot climbing (double rope climbing) emphasized in this manual is made specifically for arborists. This rope is made to accommodate two of the factors needed for the technique involved. It is flexible enough to form the friction knots. And it stands up to the heat generated by the use of the friction knots better than other types of climbing ropes. If you will be climbing using only the single rope technique (SRT), the static climbing rope used for caving and rappelling (a controlled descent down a fixed rope) may be used.
Arborist ropes are of either 12 or 16 strand construction. Sixteen strand rope is braided around a core that holds it in its round cross section. Twelve strand rope may or may not have a core. For nonprofessional tree climbing, 12 strand is more than adequate. Just remember that an arborist rope will take a friction hitch m: can be used in single rope technique (SRT). But, you cannot use static rope for friction hitch climbing.
For most trees in the midwest, 100 feet of rope is adequate. I frequently carry only a 75 foot rope and, when weight is a consideration, even a 50 footer. You need to be inventive to use this short a rope though!.
