Well.. They all have different personalities. Mine as a 4 year old and now is a little higher strung then the one we're getting ready to buy. He has alot more go and likes to move out at a faster pace, gets impatient quickly and is alittle less tolerent of mixed cues. Whereas the 4 year old we are buying is very laid back and doesnt react to mixed cues. He's very, very mellow. Some of them do need more experienced riders, just like any other horse. Some are a little more lazy and wont work if they don't have to, some will. It all depends on the horse. Some will take advantage of you and some wont. The breeder we are going through, McGuire Farms, the lady says that some of her horses are not fit for timid or beginner riders, because they will take advantage of your timidness, some are very good with beginner riders. Some will respond more actively to mixed cues then others. She has a mare that is a very gentle, sound trail horse but if you don't know what your doing, she doesnt like to work and wont if she doesnt have to. She said that compared to other breeds they are considered to be more gentle and calm in nature but they are all different.
