You talk about a lot of different arguements. Are you ready to read this long opinion?

About the overhyped Grand Line: you're completely right. I said the same thing in another forum, in another site, in another world.
 * 1) All the islands, except for Little Garden, are pretty normal. Whiskey Peak, Water 7, Jaya, Alabasta... Please notice that it is only a few years that Thriller Bark is in the Gran Line. And for Skypiea, most people don't even knows that it exists, so the "graveyard of the pirates" epiteth is based neither on it... but then why?
 * 2) Please notice that a crew different from the Straw Hats would have not had problems in Straw Hats route, except for Whiskey Peak and Little Garden. A normal crew would have completely ignored Alabasta's trouble; they would have not awaken the interest of CP9; they would have ignored Skypiea, going ahead after Jaya; they would have not awaken the interest of Kizaru while on Sabaody.
 * 3) I read that a pirate spends most of his time on the sea. Oh, it's true... in reality. But in One Piece Oda often skips the travels, and all the fights occurr on the islands. By the way, Oda decided in this way because otherwise it would be too strange if the Merry/Sunny had always survived without major damages. The only "real" naval fights are when Marines shot canonn balls and Luffy deflects them.
 * 4) I admit that the Acqua Laguna, Florian Triangle, Knock Up Stream are interesting phenomenons, but actually the Florian Triangle was a problem because of Thriller Bark (an island).
 * 5) I'm prety sure that Luffy will never reach an island like Raijin (Urogue's), Apoo's or Bege's.

About the reverse journey through Fisman Island, it's very simple. Maybe there is a similar island. Or... the resin is storable in barrels (not shown, but obvious) and so someone can bring it to the New World. The resin resists even outside Sabaody, if the ship remains underwater. It is shown with Whitebeard's secret ship at Marineford. So: coating a ship while it is already underwater would be possible. If you're asking me how to "sink" a ship... hey who knows!!

About leaving the Grand Line. First of all, there is also the question of reaching a Sea from another one: Sanji was born in North but he grew up in East and Ace did the same being born in South. For the problem I exposed, maybe there are "holes" in the Red Line which links the four Seas. For your problem, even the Reverse Mountain goes in only one sense it doesn't mean there is not an opposite way.
