I have a question on descenders.
I have a standard figure 8 that I have always used to do rappelling with. In caves and out I have never rappelled further than 150' but that may change in the future.
Right now I have been looking at getting a new figure 8. In particular the Petzl Pirana
I am comfortable and familiar with figure 8's and I like how this one allows you to easily lock off and be hands free with it. What I want to know is why would a rack be so much better than the pirana if I would not be crossing any knots or doing anything over 150'?
To me this seems easier and a lot less complicated (hence less likely to mess up) than any type of rack I have seen.
