Pac Designs Messenger Bag: User Feedback Please

I think the Street Scene is the new name for the PAC I worked with a few (6 or 7) years ago. It was big enough for most grocery loads. Could fit a case of 24 beers (just). No complaints with it at all.

Thought I could post in here instead of new thread...

I've had an Ultimate for the past 3 years of being a Messenger in Auckland (NZ) (previously used a horrible Ortleib)
I'm looking at buying another PAC (especially with the free postage thing happening at the moment)
I'm leaning towards a Street Scene: Small. I only need it for mucking about on weekends and stuff, the Ultimate is kinda too big to lug about everywhere with me (plus it stinks, no matter how much I wash it)
What kind of sizes are the Street Scene bags? I have looked at the measurements on the website but I can't seem to picture them too well, does anyone have any pics of Street Scene bags in use? Or has anyone had any experience with one?

Very much appreciated.
