What is 665's rated film speed ? I know with Type 55 , I expose it at EI 25 , to get the negs I like , and I think Polaroid rates Type 55 at EI 50 , I would think you could rate it lower and run a few tests to see how dense the negs can get , before becoming " bulletproof " and block up. Good Luck , and let us know what results you get .
