You should definitely pick OP back up. This current arc beats anything Naruto has put out in years. Romance isn't a factor in OP, but I've said it before, I really do believe that at the end of the series, Nami will be holding a little miniature version of Luffy that'll be talking about how he wasn't to be the pirate King.
I'll consider though I've only watched the anime. I Got Up To The part where the little moose?? Was introduced I believe. A little after that actually.
And @rocci
It's apparently quite hard for him since they disappeared in one another's eyes. Lol
