@bwilli88, didja ask @Spaghetti Legs what he used? I have a Ritchey Breakaway that came with a custom case, not sure how the S&S coupler would work. @VRJAKE has an S&S coupled bike, and I know he has a special hard case for it.
If the fork requires removing to pack, I'd definitely go with sealed bearings - much cleaner.
I'm able to fit fenders for my breakaway in the case.
Pro tip: pack the handlebars in your carry on luggage, if you're flying. They actually don't take up much room, as you can pack around them.
