It might help by understanding the ‘whys’ of what’s expected in your horse, first.
The good hunter needs to stand still at checks because movement creates noise and can make it difficult to hear the hounds. (And of course it’s annoying for others if your horse bumps them).
The good hunter needs to be controllable (and there is some latitude here, I hunted one for 20 years that didn’t always have brakes but did always have steering:)) so as to not be a danger to other horses and riders, and to not interfere with sport (you don’t want to pass the field master and risk disturbing hounds, whether on a run or trying to find their quarry).
Importantly for the rider, you want to be able to enjoy watching the hounds, it’s never pleasant to spend hours having to work hard to keep a horse under control.
#1 universal rule of hunting: hounds have right of way and you need a horse that can grind to a halt NOW to let a hound pass, a horse that won’t kick hounds, and a horse that’s okay with hounds materializing from any direction at any given time, a horse that’s okay with the sound of 40 or more hounds in chorus and running hard.
With all of that in mind- sure, if a horse is being a spaz in a group of other horses, taking it back behind and getting where you can just do small circles quietly is the way to go. You’ll see at Arapahoe that the country is well suited to this.
It’s also important to set your horse up for success- if you’ve done a fair amount of eventing, your horse may be okay with another horse some distance away jumping xc at the same time as you. But, is your horse accustomed to moving at speed in a group is a question you need to know the answer to. And can your horse handle lots of hounds, the horn, staff galloping by, etc. You’ll get that picture when you car follow.
It’s always a good idea to arrive knowing what your horse will do in a group, so trail rides in advance of hunting (at all speeds) are good. For your horse’s first hunt, the ideal day is probably one during the week when there are fewer people out, and the ideal scenario is, ride in the back of the hilltopper field with someone on a real steady eddy experienced hunter who knows the game. Hopefully that person will be someone who, if you find your horse is just miserable/fried/whatever, will go back to the trailers with you if need be.
I’m articulating the ‘be prepared for anything’ scenario- you may indeed find that your horse takes to it like a duck to water in which case you just go with the flow! Important caveat, however. Many horses are ‘just fine’ for the first 3 to 5 outings and there’s a threshhold to be met after that- when they know where they are going and what they are going to be doing- that is an acid test for most. I had one on trial years ago, went nicely the first two times, third time, stepped off the trailer in a lather and, long story short, after 30 minutes I took him back to trailers- his brain just wasn’t wired for hunting.
