When I first took lessons in November of 09, my teacher told me that to make a tight turn, you rein your horse to whatever direction you're going (it probably doesn't matter whether it's neck reining or direct reining, as long as the horse actually turns...), and tuck your INSIDE leg into the horse's side so that his hindquarters will move away from the pressure.
That always worked for me, and makes the most sense when I think about it.
But, at the trail-riding ranch where I work, I'm now being told I should apply pressure with my OUTSIDE leg, because when you make a tight turn you're not engaging the hindquarters at all, and tapping them on the outside of the turn encourages them to complete it -- but isn't that how you side-pass?
So, for the sake of me not getting yelled at by my trail boss, I'd like to clear this up. Which side is correct? Is there a technique to the outside leg that I'm not understanding that makes it a better choice?
Also, we have a trainer who comes out to work with our 3-year-old filly a couple times a week, and in watching her do tight turns on the property, I can clearly see she's using her INSIDE leg to help the filly turn.
