I like how equally challenging both detour are.
Sing It requires signing a song in Italian, and both racers have to be synchronized, of course. I like the boat couple's reactions sometimes.
It gives the teams a clue how well they're doing.
Bring It may be a physical task, but it does not require a judge's approval, so teams should just have a good sense of direction, aside from physical strength.
A W-turn here would've been fine, but the way this leg started with the bus ride, maybe it's better on a different leg.
