One of the best chapters we've had. That guy above said Oda dragged it out with ten pages of Usopp sniping, I thought it was perfect. It reinforces the facts that:
1. Usopp's intelligence more than makes up for his lack of might. It wasn't his superiors, Law or Luffy, that knocked out Sugar, it was Usopp, the weakest and the coward. Just goes to show Oda hasn't come close to forgetting his point that each Strawhat does some kind of role to their strengths
2. It shows Usopp's brilliance. While not as smart as Nami or Robin, it shows that Usopp was able to accurately make that long process work, as well as build up to the Doffy fight a bit more.
I loved the chapter.
