I've decided to ride my horse in my double bridle.
I used to use one on my old warmblood sometimes and I've been riding my tb in it recently and he's going well.
I was told by a judge that most judges don't mind how you hold the reins in hacking classes but they pay attention to the way you hold them and use them in riders classes.
I was taught:
Snaffle rein under finger 3
Curb rein under finger 2
Both reins held by the thumb
Is this correct?
