Advice needed!!!!

So I am going to be horse searching when I get down to Texas. I sold my gelding sherman. I really want to get a baby that I can show in halter and longe line and then ride when it gets older. I would want to show at breed show levels. I will want to show APHA and PtHA.

So my question is......what do you look for comformationally in a baby when you are looking. I know its hard to tell because they are still developing but still what do you look for.

Seconed what are some good halter sires? I know of a few. Also if you happen to know of any halter babies for sale in the texas area or south oklahoma area but preferably near houston but I will drive a little ways to take a look at the right horse.

Any help or advice will be appreaciated.

Anyone that tells you they can tell a "good horse" from a "bad horse" before the horse is basically done growing and developing is full of crock.
Personally, I look at bloodlines and performance records of related horses and parents/grandparents. It is really tough to breed two 5/10 horses and get a 10/10, you need to start with two good horses in order to make another.
I would still do all the normal tests and a vet check and all and just make sure the horse has straight legs that function properly. And definitely look at personality! If you don't get along with the horse when it's young, you aren't magically going to get along with it later. I've handled quite a few young horses (<2 years) and the ones with good temperament do have the ability to stand quietly, and behave. It's only the ones that really are trouble that behave like a handful.
Good luck!
