Which trainers do you avoid like the plague?

Trainers are only as good as the horses they are given to train. Admittedly some do a bit better job but at the end of the day they are not in it for the punter. I recall a friend several years ago before he died, having a horse with a trainer beginning with Sir and a surname similar to a well known punchy politician. In the twelve months his horse was at the stable he received 14 phone calls early in the morning telling him to back a horse that day. 13 won. - Then he took his horse away as the training fees were too high - I let him know I thought he was a Rodney! Personally I would back any trainers horses, they all have their idiosyncrasies but that is the fun of it !
