I can't agree on the short time for Taste Your Salami DETOUR. I think it took a long time for Brendon and Rachel, although I don't have any idea about Kerri/Stacey. That was a hard DETOUR. They had to taste and memorize at the Gastronomico Salumeria and then walk somewhere that was not in the same neighborhood, then try to name, walk back to Gastronomico Salumeria and repeat that cycle a few times. I am going to guess it took more than 30 minutes, but obviously I don't know.
I do agree that cleaning a statue was a poor choice for a DETOUR because it was too easy.
The "land a mini-helicopter" challenge for the FAST FORWARD looked extremely tricky to me. Maybe the remaining David could have done it quickly (although he would have been foolish to try given the experience Art and JJ had gained on that task by that time).
Rappeling was pretty boring, except for "if you don't get the clue in 2 minutes you have to go back to the top and start over."
