New vs. Old Selle Italia Flite: differences more than skin deep?

I’ve been riding a Flite for quite a while, but a new bike has inspired one of those periodic quests for a new saddle. One I haven’t tried yet is the “updated-look” Flite. Can anyone tell me whether the new-look saddle rides differently to the old one? The new one seems a bit flatter across the top… anyone ridden both? By “old” I mean this version:

And “new” would be this guy:
