I always liked how they introduced the Greed Island concept even before the Yorknew arc. Also, I know it happened a few chapters ago. But, Kurapika's chains are awesome.
The arc is up for a great start. Gon and Killua are going to the auction for Greed Island and Kurapika is going there for his clan's eyes. This arc is my second favourite in the manga, and that there are two "stories" and that the main characters don't share the same motivation is one of the reason I like it so much.
Yeah, Kurapika chains are definitely awesome. I didn't actually specify that in that chapter discussion but I love them. Anyway yeah, it's pretty awesome how early they set-up Greed Island.
