When your out on the rode like that, forget about carrying all that extra crap. Its a pain and nobodys going to help you, plus if you do carry it as opposed to leaving it in a hotel, good luck on explaining it to customs everyday. Remember you are on the road to work not a vacation. Not to mention the fact most of your layovers will probably be less than 36 hrs and you will spend the majority of that time recovering for the next flight.
