This is such a great response - thank you so much
@leechiyong. I feel that you have cut to the heart of the matter. However, I seem to be on a weird roll with lv.com - the last bag on my wishlist, the Motherboard Crown Frame, came up for sale today after I wrote my initial message in this thread, and I purchased it. This is by far the bag I wanted most - except I was under the impression from previous posts that it never made it to market. So, as long as the bag ships and there is nothing wrong with it, it seems likely I will be returning both the Reverse PM and the Nano Speedy!

What a weird week it has been... Thank you again.
