Just barely caught up! Though I'm definitely pleased to see that the fan translations have improved since the travesties that were chapters 341 and 342, I'm for sure going to subscribe to Weekly Shonen Jump from now on (not to mention purchase the backlog chapters).
I'll save any real thoughts for once I've read them, but to just quickly comment, I'm really enjoying the new arc so far: especially the return of Kurapika and Leorio, who were my favorites way back in the time before Greed Island and Chimera Ant (each are now my 2nd and 1st favorite arcs, respectively). Perhaps the two of them can dethrone Killua and reclaim their crown; they're certainly on the right track.
Also, Ging, way to live up to your hype dude. Can't wait to see his hatsu, can't wait to see the Dark Continent, can't wait to see where this is all heading! Mega excited.
