Big shoots = Big money, if your willing to pay £500-£1000 for a days shooting & stand on a peg shooting bird after bird where is the sport or skill in that, you also find on some of the big shoots the attitude is still THEM & US which i do not agree with.
I personally like the smaller shoots, everybody talks to each other & has a bit of banter, its not all about the bag numbers at the end of the day, its about that one memorable shot, that one high bird & the good company you have been with all day.
