Shonen Jump is ok. They don't translate things as they should though. They like to alter certain dialogue from what it should be and some term translations are wrong. The Going Merry is not supposed to be the "Merry Go" O_o.
Btw, I couldn't find the previous One Piece thread, so I sorry about that, and that person got like all the names wrong. O_o Ruffy = Luffy, Lysopp = Usopp, and Zorro = Zoro. Must be reading a weird translation of the stuff.
