I've been convinced that the purchase of a Tri-Star is the way to go. Unfortunately my preferred colour (Cardinal) is not available at present but that is another story.
I realised though that using the TS as a carry on I will not be taking my old faithful backpack with me - and I will need a backpack for the week or so I'm in NYC later this year with my wife.
I'd thought that the packing cube/backpack would be the solution but am questioning its strength and suitability to carry a camera and the other assorted stuff you wander around a city with for a day.
