There's more info in my thread "Micro loose-leaf binder" a few threads down. I really like the Filofax GMES you mention (where were you for my thread? ), although it seems like it's going to be ~0.6-0.7 inches larger on both dimensions (based on FF's smallest "pocket" paper size) .... but it might still fit in a shirt pocket, if not invisibly. Anyways, think I might stick with this one for a bit for its size - it still has some serviceable life left, and I have a stack of pages that should last a while. I'll be looking for that Filofax to check out though - thanks for the suggestion.
