When I mentioned hackamores, I meant bosal.The book I mentioned goes into great detail on it's use, but also covers use of the snaffle.
Most mules I started, I used the bosal.Mules will cheat on you pretty fast and will try different ways to get away from the snaffle because it rubs across their bars.Then you start to use a cavesson and the mule hate it even more.With that,the mule can't get away from pressure.
I'm with you,let them run and then make them run a bit more.
Amazon has that book.
