Interesting, I can't tell by their website what it might be closer to, open shows or h/j type. I'm thinking more open since they have several breed classes and such. But pictures look a lot like h/js
Let me answer from the perspective of a h/j type hunter rider!
Would my horse place? - no idea. :) totally depends on how your horse goes and the competition he's against!
Do all hunt shows have flat divisions? (He is only 4 so no jumping) - they should.
Do I have to change my bit? (It's an english port w/ a chain) - what are the sides like? Judges prefer snaffle type bits, but you once the bit is in the horse's mouth you can't always tell what it is: if it's a snaffle or say, a dr bristol. Unless the sides are different. There was an undersaddle class where it came down to 2 horses. The judge picked the snaffle over the kimberwicke simply because a snaffle is much milder. If your horse goes well in a snaffle I say put him in a snaffle.
I need a new jacket, where do I get an affordable one and what does it need to look like? I am assuming AQHA and hunt jackets are they the same? They fit the same but usually colors are more traditional. Navy is classic. Darker and lighter greys and sometimes browns are great. Black with a subtle pattern in coming in huge. But hunters generally avoid hunter greens, teals, light tans, etc that I see mainly in the breed show world. Ebay is a fabulous place to look. The Dover clearance section also has some great deals.
I need new boots and want zip ones, can I get them for for under $200? Cheap ones? Absolutely. More quality ones? You can if you look around long enough! I found my Ariats new on Ebay for $150! No zippers though...
Can I use my tail? Do I always have to braid?[/quote] Yes, but skimpy tail is always better then a poorly done fake. Not as important to HJers as in the QH people. Most people don't braid tails unless they're doing a rated show. Even then I don't unless it's a really big show or an important class.
