I have been riding for 6 years, but have never owned a horse. I am an advanced rider, I am into hunters/jumpers, and I have ridden many different breeds of horses, from QHs to Morabs. I want a breed that has some 'go' in it, but is easy to handle and won't bolt on me. I am also into breeds that are able to jump up to 3 feet or higher, as I currently am jumping around 2 feet. The breed must be not too tiny for a 150 lb person, but not to tall for kids/teens. It should usually have a good temperament, meaning around a 2 or 3, no more then a 5, if you rated it 1 the calmest, 10 the most temperamental. What are some breeds that meet these specifications? Also would want a horse that could be used for lessons if needed.
