Okay, I've just had a private consultation in my walk-in closet with my Ada (seeing as I haven't told hubby about this bag purchase yet!).
As far as the studs go....
1) From one end of the handle across to the other end of the handle, there are 8 studs across.
2) There are 8 double studs from the handle down to the base of the bag.
3) The side pockets each have 7 studs across the top of the pocket
4) The base of the bag has just 1 stud in each corner of the bag (total of 4).
Looking at the pics of Halzer's bag and counting the studs, it looks to me as though we have the same size Ada, ie just the right size
If there were two sizes of Adas, I'm not sure which size this is, small or large, but any smaller and I think we'd be in Jillian territory. I used a tape measure and my (stuffed with paper) Ada is approx 15' x 12' x 6'.
In the box, with packing, the weight mentioned on the USPS form was 3lbs 14ozs, which was a lot lighter than I expected.
