I own and ride a 12.3hh Exmoor gelding. I'm 5'1" and wiegh 8 stones so he's just right for me. I've had him from a 6 month old foal. He's a lovely little ride, intelligent, quick, sometimes stroppy and he's not suitable for a child. He hacks out alone or in company, does a bit of jumping and dressage (ver simple dressage tho). I've ben riding over 40 years (I'm 50) and I want something fairly lively and not too tall so he fits the bill perfectly.
