Good for you to find a new way to communicate with your horses.
Just keep learning more, some you may like, some you won’t so much, but be patient and eventually you will know enough to properly sort thru all the to you new discipline brings to your communicating and what else you may already have better skills for.
What was hard and “against my religion” when learning reining was the behind the bit experience a really finely tuned horse has for someone used to more of a connection with rein aids.
Once I learned to use my weight and legs more precisely for the task of keeping a horse in front of the leg and engaged, more than is really necessary in English riding, I learned to keep horses collected under myself just fine, without them after a bit starting to cruise on and fall onto their forehand, like they would when trying English riding only off the seat and legs, no bridle or neck strap.
You will rarely see that kind of total control on a dressage horse, even at the highest levels, one that can be ridden without any bridle or neck strap and still perform consistently without their performance starting to degrade.
There are few that go there at all.
That is common with most well trained, finished reiners.
The first a reining trainer will ask from an English rider is to stick them in a round pen with a reining schoolmaster type horse, have them fold their arms in front of them, so they are not even used for balance and then learn to use the weight, legs and voice propely, while keeping the horse well under itself, by the way we ask the horse to work.
Lots of transitions properly executed, catching the horse when it is starting to cruise along so it gets back in proper working mode will go a long way.
Asking the new to reining rider learn the kind of body control of themselves and the horse that will let them later, once in the larger arena or anywhere, have that same kind of control, which is the basics of reining for everything else.
Reining is about timing and precision, something that later will translate to any other we may do.
Similar to what dressage is to English riding, a base of training techniques that are applicable to any other kind of riding.
Hope that makes sense?
