Desy, I know exactly what you're saying. My AQHA gelding is an ex Ranch/Barrel horse, so he has speed, but he's also able to be turned down to where a 6-year-old can ride him around. If you really want a new horse, I'd look for something like him. Well trained (too well trained for a heavy-handed beginner, granted. Too many buttons to push!), quiet when you want him to be, but able to be turned on to a 'hot' horse just by adjusting your hands and seat. My horse isn't nutty in the slightest, but he's definitely a fun ride!
