I have fought fireblight on my quince for 8 years and have had enough, they 
are getting chopped down once the harvest is in this year.  This is with 
agrimycin etc sprays.  I had three varieties and all were bad (one already 
died from the infection).  They also were the primary source of later season 
fireblight on my apples.  

So, Pinapple, Smyrna, and Aromatnaya were no good and more generally if you 
have blight problems already I would stay away from quince: they can greatly 
worsen the situation since they will be a reservoir of the disease.

Stephen, I don't think Regalia helps with fireblight, at least its not on the 
label.
