Getting back should be the same thing, only in reverse.
There has been discussion on the 'Leap of Faith' stash. Not sure, but it may be made so that bolts bounce off the invisible walkway, then you're not constantly falling off the edge and having to reload and try again.
The one sad thing about it is that, when you get there, the contents of the stash aren't really worth all the trouble of getting to it. So most will probably do it once, then not bother in future LA games.
A preoccupation with the next world is a clear indication of an inability to cope credibly with this one.
