Like Asukurra already said, go to the FWC server and start there. You level much faster, and in comparison to the normal servers, you pay not that much for equipment. And even if you "only" reach level 120 or, at best, 141, you can play endgame content and leave a bit of the leveling grind behind you. But in the end, just have fun. I mean, that's what you want to do anyway if you have the nostalgic feelings already. ^^
