You're no doubt more knowledgeable than I on this subject, Buenchico, and I'm in no position to disagree, but just an observation - Catalan is clearly far more closely related to Provencal than it is to Spanish, and in my experience (admittedly limited to a few visits to Barcelona and the surrounding countryside) Catalans regard the Spanish as a foreign people and Spanish as a foreign language; more than once I have been told things like "Oh, that's the way they do it in Spain, not here" or "In Spain they would call it........" or "Next time I go to Spain....."
