Also, running your horse into walls is only going to give him some weird corner phobia, I've seen it happen with a lot of breed shown horses (that's how they teach them to be "straight" in some barns).
I recommend lunging the horse with proper lunging equipment over caveletti. Under saddle, keep the figures simple and don't do any shallower of a turn than a circle with a 20m diameter. Ride the horse so his shoulders point straight in front of your knees and keep your shoulders square, hands down, together and quiet. You yourself have to be in perfect balance before you can expect it from your horse.
I also recommend finding a trainer in your area that can help you out by pointing things out from the ground and making suggestions on how to fix them. It is hard to see how a horse is traveling from the saddle. Good luck!
