trend horses/trainers..

Are there any among you who study this,and get the most out of it,i mean on a more deeper leval,where you have watched lots of replays of horse races/combined with studying the previous years formbook,and on the back of this finding examples of horses that are on your radar,and worth following or being on-side with for the duration of the forthcoming season.And when you can recall similar trends from the past,where a trainer has had a very similar type of horse,that has gone on to better things,and you find one in the form book that reminds you of such a horse,it more often than not becomes profitable to follow in the future,i think the trends change a bit from time to time,and there will always be something new on the horizon,but overall if you put yourself in the mind-set of certain trainers,there methods do not change much year in tyear out.And the good wood in the yard is easier fish out.Anyone understand what im saying or use variations of this.
