My point was much more general, and really doesn’t have much to do with anyone’s specific history or resume.
My point was that they are a useful tool for certain horses and certain situations (I gave an example), but they are NOT a one size fits all, universal tool.
Now, I’ll allow, if you’re in program that’s entirely built on the German system and using purpose bred dressage horses, they are MORE likely to be a useful tool.
But still not universal, still not one size fits all, especially not when you expand the audience to all horses and less than classically educated riders.
