Chicken or Egg?

So if you've seen my post on the Ledbury conversion, you know that I essentially took an older model bag (Ledbury) and customised it so I was able to wear it with a strap, effectively creating a Small Bayswater Satchel - hence a newer model.

You could say it's ironic (though it's really just the logic precursor) that whereas I took the SBS as an inspiration to customise the Ledbury, Mulberry took the Ledbury as the inspiration for the SBS.

So what's better? Ledbury or SBS? There's only one way to find out...
