I sold off all of my English gear a few months ago. I bought a very nice barrel saddle and fancy bling headstall, and I never planned on riding English again, since I just ride trails. I'm kicking myself for that now!
I mostly get made fun of for riding in an English saddle with all my western stuff and neck reining. Apparently it's frowned upon. I don't care much, I laugh at myself for it as well.
As for the leg cues, when you ride English, you squeeze right leg to go right and left leg to go left. Just like in direct reining, left hand to go left.
I know there is a requirement for using the outside leg as well, however this is how I think about it and basically the only way I can explain it.
In the years I've ridden western horses, I have picked up that they are taught the opposite. They are suppose to move against the pressure, so when you turn right, you squeeze your left leg. That goes along with the neck reining, when you lay the reins across the neck to the right, the horse goes left.
Sorry if that makes no sense, I'm trying to make sense of it in my own head still...either way, that is how I ride and my mare seems to know what I want. Now if I jump on my old barrel mare, I can give her any leg cue and she will only listen to her neck reins. If I jump on my friends western trail horse and give the leg cues I'm used to, she has NO idea what I want.
I'm looking for a new bit so that I can get rid of the gag bit, but she WAY prefers that to the double jointed snaffle!
