i'm wondering which cave is the very first which deliberately uses dancing fly formations?  
  
at least this one,  Arno  dash 8 cave 11 (from 2003), was my first "experiment". well, as i remember, i discovered the f&F formation by chance and built a cave around it... ;-)  
but: does anyone know an older cave with dff's?

i have no idea which cave was a "godfather of the dff" but i realy like the golden oldie series! :) true masterpieces! especially 5th cave - the great escape from  nesdori . this is mindblowing with your modifications.  nesdori  said that this cave is about 33 years old!   
imo one of the best caves ever:)
