I forget the name of the hold (Spyder help!!) but it is still commonly used today. I like it when I need an opening inside rein for something and because I have brachydactyly I am basically inept at independently using the snaffle and curb in a traditional hold. Arlene 'Tuny' Page is such a nice rider I'm sure she has a way better reason for using it on that horse though lol :P
There is a rhyme and a reason for every hold in the double and it is kind of sad to see the majority of people only ever exposed to one hold!! In that same magazine, Kyra Kyrklund illustrates the Fillis hold for those new to the double - which I find interesting as it can be such a severe hold. But for the rider with quiet hands just learning to ride in the double, it makes sense.
They say money doesn't buy happiness -- well happiness doesn't buy horses!
