that bracket is also very tough too. I don't think you can say that about 5a. 5a was very tough last year,with some very loaded brackets. But i do agree with that 4a is a very tough class and maybe one of the toughest out of all of them. 4a and 5a is usually always the toughest i think. But it all depends on the weight classes some of the time because some can be very loaded in a classification and some other classification can be very weak. So it all depends on the year.
