In reply to flopsicle:
Thanks to everyone for the replies. My daughter's a very obsessed climber + general playground acrobatics (monkeybars backwards, cargo nets from underneath etc etc). The confidence rope is without a doubt for my nerves watching her fly up stuff like a rat up a drain pipe! That said, there's part of me thinking it's overkill - there's 2 adults, she does as she's told and if it all goes belly up we have our very own nurse in the shape of my pal.
I had initially thought of Ptarmigan ascent and tourist descent but switched because I thought it'd motivate the little 'un through the boring bit knowing I was going to decide from the top whether she gets the exciting descent. Thinking about it though, I think Ptarmigan up is probably the better deal.
