I guess my 1st question is did you get rid of all your panerai just so that you can be a bit more focused in your collection?
What did you like/not like about your previous Panerai collection?
Was the 47mm case size on the 305 a good size on your wrist? Was the heft of 172 a bit too much for you?
While I would be leaning toward the 127 personally but I would argue that PAM40 seem to offer 'something' you didn't have before: the T dial and the lighter weight of the 44mm titanium casing?
And finally, what's wrong w/ getting both?
