Some people around where I'm from ride western "split reigned" like english. English you give pressure and dort of pull back the direction you want to go and you usually have to use your leg. The horse I ride if I want to turn left across the arena then go straight over a pole I have to push with my left leg, pull with my left rein, and hold my right rein to get him to bend propperly. Basically no matter which way you do it you'll be pushing your horse into a turn.
