"Oh, I see. Well, I really like the 1 3/4" dimension at the nut. It's better for chording and fingerpicking.

The OM's have the 1-3/4" nut. The OOO's usually have 1-11/16", the EC is an exception.

I have an OM-28 Marquis, it sounds far better than any OOO-28EC I've ever played or heard - not 'boxy' like the EC, and better bass, generally a richer sound (as you would probably expect from the longer scale and adirondack top). If a Marquis is too dear, I'd recommend the OM-28V, or failing that, the OM-21 (a 'Special' is even better if you can find one). All great guitars.

Hamish, I played a couple of Brooks at IM last year - they were jaw-dropping! Keep well fella! :0)
