That map looks about the same as the one I found.

As far as how One Piece I want to go, I don't want the OP characters, I want the characters to be challenged. I want the memorable encounters, the fun role play, and the adventures on the way to their main goal: some insane treasure that everyone wants.

Though an idea did hit me at work yesterday, have them not sure where the treasure is. But they have clues. The person who left the treasure left markers to follow. So, they find one marker, it leads them to another planet where they have some short adventures and discover the next marker.

The neogi slave ship could be a fun encounter along the way.
