Okay a few questions (not on a high horse - honestly asking).
So you say she's a grade horse but I assume she has good breedable attributes such as a god conformation and great temperament that you'd like to pass on which is why the grade part / pedigree doesn't matter, correct? That said, what are your goals for breeding? Do you want a western pony, a sport pony? There's a lot out there and being picky in who you breed to is a must these days imo as there is SO much out there and not all of it is quality.
Now I WILL add in this caviat b/c it's how I feel, for moral reasons, that unless you're breeding an incredibly mare both talent and conformation wise, then pedigree absolutely SHOULD matter. And regardless, pedigree should be in the very least considered when reviewing stallions not just for suitability but to give you an idea of their lineage and what they are likely to produce, though it's breeding - there are NO guarantees.
And finally - I just like to point out that there is more cost that goes into breeding than there is in buying a baby/foal that is suiable these days. Most people are under the misconception that it's cheaper to breed than buy, however that's not the case MOST of the time. I know this b/c my mare is bred to foal in May 09, and will likely be bred back for a 2010 baby.
Just my two (or three) cents.
Sorry, should of put most of that in the post xD
Yes, her conformation is good(in my opinion). The baby is *hopefully* going to be used for my niece as a show/pleasure pony(doesn't matter which discipline, probably english, maybe western) but it needs to be tall/big enough for me to be able to train it(hence why i want a larger stud).
She's a good, level headed pony. she's got the pony attitude though, which i like.
the reason why i say it doesn't matter with pedigree for us is because we aren't planning on going to any rated shows or anything like that with the baby. i know a lot of traits have to do with parents, grandparents, etc. but as far as it being REGISTERED, we don't care.
with that being said,
how big is too big for the stud? how many hands high should the sire be at MOST?
here is a picture of her running around in the pasture(not the best confo. pic, but its all i got):
