If you are tall, buy the optional, longer (12", IIRC) handlepost.
IMO, (i) the Swift is the best airline-legal "suitcase bike", and by far the fastest to pack and unpack. 5 minutes, each way, without rushing; and (ii) the wheelbase gives it a stability that nothing else on ISO 406 can match.
I like the ride of my steel frame Swift much more than the Al frame, but a good saddle and shorts make the Al frame bearable.
The 11 speed Alfine would be the IGH of choice.
