A couple of years ago at Man I took off behind a 757 with very little separation and encountered pretty bad wake vortex (a report was filed), I was flying an A320 . So now I always request two mins. Correct me if I am wrong but I believe in the states that ATC treat the 757 as a heavy. I believe the FAA concluded that the vortex from the wing was significantly higher than from other aircraft of that weight.( < 136t)
