Ok so we bought this quarter horse gelding whos always been ridden western and he neck reins like a dream. But i've always ridden english.. And if you try to steer him without neck reining he hates it, he throws his head and just throws a fit. Is there a way to get him used to this? He's for my nieces and I really want to teach them english because I know more about it plus they would look silly in a show ring neck reining with english tack on

or should we just leave him along and ride him western since he is 12 years old?!?! We've even tried it with no bit just halter and he still throws a fit. Plus if you raise your hand just to pet his face he jerks back like your going to hit him and i've never hit him.. any suggestions.
