What is the safest and easiest rappelling device?
So I made a mistake. I took my wife for her first rappelling trip and did BattleCreek Falls. She wasn't in the falls itself, but it was too loud to communicate properly and that left her with a lot of unanswered questions and concerns. She did it like a champ, but told me that she only endured it and did not enjoy it.
I am taking her Canyoneering next month with @Deathcricket down in Zion and part of me is concerned that this may be the only trip she ever does. I want to make her feel as safe and solid as possible, so I am looking for some input in advance.
Currently I have a Pirana that I was planning on her using, but I am wondering if she would be better off with a Totem, or a grigri type device.
What do you guys suggest is the best device to make a complete newbie (with a fear of heights) feel safe and secure as they rappel down?
What advice would you give me to get her ready for next month?
Thanks
