Well all these responses sure make me feel a heck of a lot better!
I have NEVER focused on diagonals. Riding a western horse at a jog in the show ring ... well, you don't have to! Out for general riding, I do post when we are at a good working trot but 99% of the time I am on the right diagonal. It is just comfortable for this.
This fall, I started trying to force myself and FEEL which one I was on. Plus, I figure it has got to be annoying for my horse if I am always riding on the same diagonal. For his physical health, I really should switch it up. So I've been working on it, but I do find myself glancing down a lot to check!
Diagonals, I think, are much harder to feel than what lead your horse is on when loping. I never have to look down for the lope.

It is not enough to know how to ride; one must know how to fall.
