That hack is not a bad hack, but I still prefer a little S over that one.
The thing about hackamore is that it's going to take away from the bend on your horse, and the lift. Good for bendy horses, but not good if they're stiff. Some like it, some hate it. Lots of people do use them though. Brittany Pozzi has Duke in something similar sometimes.
If he rides good in a bit, why would you want to switch to a hack?
Pssh.I didn't pick up the wrong lead
It's called a counter canter...
...A very advanced maneuver.
