No im not collecting info, I was just curious to what people would do
Don't worry about it, it's a good question. I've even asked people the same.
I personally, dislike younger horses. I grew up riding MANY green broke, young horses. I am tired of riding and training horses and dealing with their issues. I spent more time worrying about the horse and what could happen while riding and training he/she - instead of working on me, enjoying myself and having fun.
I see people around me getting 2/3 year old OTTB's and I just shake my head - not my cup my of tea. I don't care that the horse was $200, or free, or $1,500, I don't envy them with all the crap they are going to have to go through to get the horse to the point of education/training/level that they have hopes to get he/she too.
I personally, would rather get a horse that is older and has alot of time under saddle. It is a pleasure being on a horse that already knows what it is that I am asking. It is wonderful to focus on myself *seat, legs, upper body, hands, elbows, chest* while in the saddle knowing that my horse will put up with whatever it is that I am doing and just get the job done.
I like being on a horse that knows what he/she is doing. More relaxing, more enjoyable for me.
I've spent years riding unpredictable youngin's - and I'm not doing it again. Don't get me wrong, it taught me alot. The experiences I've obtained while working, riding, training young horses have made me the rider I am today, but on the other side of the spectrum, I've gathered many holes in my training because of it - due to putting so much effort and attention to the horse, I forgot about me.
