Re: First ascent 20ft? I'd agree with a simple prussik system.
However, when I do projects where I use ropes and ascenders, in lieu of gaffs,
I use a Petzl mini-traxion at my waist and use it set as an ascender. Along with that I use a Petzl Tibloc, along with a biner and footloop. This system is much cheaper than buying sets of handled ascenders, and it has allowed me to shinny straight up a rope as much as 140' with very little effort.
At something like 20' that system is useable, but buying two lengths of prussik cord, tying them into loops using a double-fishermans, and then tying prussik knots on your main line is probably the easiest/cheapest way of doing it, while staying safe. |
