I have to agree with this. Even though I love jumping so much and fine flat work/dressage a pain at times it is still extreamly important. Looking back at it one of my first riding teachers was a dressage rider and told me that jumping is jump flat work with obstucles in the way. (not saying jumping is easy) and those riders that don't take time to pratice on the flat are usualy the ibes that struggle with jumping. If my horse isn't lisening to me went where jumping; the next time I ride I make sure to school her on the flat until she is really responding. ^^ Out of my two (only two in the winter sadly) rides a week one is strictly work on the flat and I usually get two or three jumping courses in on the other day I ride the rest is dressage.
