While I was in NYC earlier this year, I saw this posh lady rocking her speedy 25 with a messenger style strap and she looked so doing it too. But what do you do when you are on a budget and can't buy a speedy b that comes with a strap? I thought of using the long thin strap from the Eva but it's too long. Then I remember my keepall comes with an adjustable strap. Sooo I borrowed it and... voola! It worked... and the wide luggage strap makes it more comfy for me to carry too.
